Title: AR possibilities
Post by: tombogan03884 on May 05, 2020, 09:44:06 PM
We all discuss optimizing our AR's for our particular use, be it SD, Shooting games, or hunting.
But has any one gone about trying ALL the variations ?
The Shrike is supposed to be a good belt feed upper, although it's kind of pointless with out F/A.
Then there's the flare Launchers, the under barrel shotguns have potential with the right ammo, but those flare launchers are TOTAL M-203   ;D
There was some one selling a cross bow upper that I never did see the point of,

And then,
Like a gift from God I saw my grail attachment
The golf ball and soda can sized cup launchers     ;D

I'll make Bill Ruger's dream come true !
I will turn every golf course into a rifle range !   ;D

Who made your driver ? Topflite ?
No, Spike's Tactical .      ;D

I have an M2037 flare gun that mounts like an M203 but it's 37mm. It's a lot of dead weight when you aren't actually using it so I took it off. I bought some bird bombs for it at a local gun show and would have bought more but someone, the ATF I think, decided they weren't legal to buy if you didn't own a farm that was sustaining crop damage and get a permit, or some such BS. I can't even buy 12 gauge bird bombs anymore. On a related topic, no more buying "gopher bombs" as I referred to the M-80-like pest control devices I bought a couple of boxes full of through the mail in the past. I told my friends that you light one and drop it down a gopher hole and it blows the gopher out of the other hole. I tossed one in my large rural-type mailbox and flipped the door shut and it blew the back wall completely off. That was more than what I expected, and me and the neighbor kid I was showing them to had a good laugh. I can see why they wouldn't want just any idiot to buy those, they might do something stupid like blow up their mailbox. ???

I always thought the AR shotgun mounts would be too clumsy if you didn't have a SBS. A 14" barrel and aluminum receiver would be about the maximum length and weight I would want to try. I think a golf ball launcher would shoot the balls so far I'd never find them again and would have to buy more balls. I like the idea of the beer can launcher better. You could drink the beer or soda, then fill the can with sand like someone told me he did with a beer can mortar 6 ounce orange juice can mortar. I might not get my 10 cent deposit back but it's worth it for the LOLs. If you get a golf ball launcher or beer can launcher you need to let us all how much fun they are so we'll know if it's worth it. I think we could come up with a new sport. Wear suits of armor and have teams shoot golf balls at each other. Forget about air-soft, forget about paintball, but don't forget your earplugs. For now I'm spending my money on something else. FedEx is a day late but my package is loaded on the delivery truck. It's a race between them and UPS today.

As soon as I saw those launchers I wanted to SHOOT a round of golf and make the game more exciting, but would M203 type sights be legal? After a year or so I started thinking maybe you could do something else with them. I would pay good money to see people dressed in suits of armor like knights of old, shooting golf balls at each other. I think a lot of people would. It sounds a whole lot better than arena football to me but, I've never been a sports fan so I don't know. "Oh it's going to be a hot one today in Miami when hometown favorites, the Massacre take on the Philadelphia Fenestrators. Next week's big game is the Tempe Templars versus the Benedictine Monks of Santa Monica. I don't think the Templars have a prayer, do you Tom?" Of course there would have to be vendors selling souvenirs, food and beverages, and it would be better than bread and circuses to entertain the masses. I see it as a business opportunity waiting to be exploited.

After seeing this jackass clip can you imagine the reaction if you took your shot at the next hole when they took theirs?

I got my XBRN177E2 upper from Brownells Thursday. It was $100 off during the last big sale, which I think is still going on. I got the 1:7" twist barrel rather than the 1:12". I don't plan on shooting 77 grain match bullets or any other long for caliber bullets out of it. I have some but they're for my 20" AR. I'm just too lazy to figure out what the velocity of the 55 and 62 grain bullets I plan on using would be from the 12.7" barrel, converting that into RPMs, and seeing if I can find someplace online that says that's fast enough to stabilize them. If they had a 1:9" twist option I would have just bought that and hoped for the best.

The "moderator" is pinned and welded, and they didn't bother to put a dab of paint over what looks like a lump of copper-based brazing. My guess is that it's a brass alloy of some kind. Since I'm putting the the upper on my old Colt AR I got a new Colt-made conversion pivot pin. This looks better that the old one I used when I only had one lower. The old one doesn't have a head on it and goes down inside the lower when you tighten it. If my lower had a fence on it instead of being a slab-side, it looks like the flat side of the head would be against the end of the fence where a normal pivot pin should be, and keep the pin from rotating when I open and close the receivers.

Colt decided to go with an 11.5" barrel and longer muzzle device on their XM177E2 reproduction. By now I thought someone would have split the difference and used a 12" barrel with a muzzle device between the size of the original and mine. IMO it would be harder to tell at a glance that it was 1/2" longer than it should be, rather than one part being 1.7" longer. But you pay your money and take what you get. The Colt really looks good but even if they weren't sold out I couldn't afford it.

Now I need to decide if I want a Right Side Folding Stock Adaptor or Left Side Folding Stock Adaptor from Deadfoot Arms. The right hand adaptor is in stock now but not the left. I can stick my M4 stock on it and have the ability to shoot with the stock folded, and forget about buying the BRN-180 upper and a stock adaptor. I already know the M16/AR-15 system inside and out, and unlike the BRN-180, spare parts are not only available for it but are abundant. I get a 20% discount at Deadfoot Arms for being a veteran, and I can save $100 off the folding stock adaptor kit by sending in my bolt carrier for them to modify, instead of buying another one in the kit. The right-hand folder would probably work best for me slinging it on my right shoulder and it's 10 bucks cheaper than the left-hand folder. I think I talked myself into it. There goes anything I had left of my $1,200 "Trump Bucks" and then some.

Cool deal. But I wouldn't buy anything with Colt on it . It's nothing but an over priced trademark put on stuff that Colt USED to make. They couldn't do that if the patents were still in force. That's why they only recently tried to resurrect the Python.
They didn't own the rights any more.

Some of the Colt and Colt Canada stuff looks pretty cool, like the M4 Monolithic with a folding sight on the gas block, and the MRR, Modular Rail Rifle that also has a monolithic upper. But like you said, Colts are overpriced. If you want something out of the ordinary there's a .50 Beowulf pistol on the market, but it's called 12.7x42mm so no one has to pay royalties to Alexander Arms. I bet you'd be the first one on your block to have one. :) And the last if your neighbors got a taste of the recoil. Here's some ammo for 2 bucks a pop and some for just $1.25. Underwood Ammo has quite an assortment of .50 Beowulf, and if you want less recoil from your .50 caliber AR pistol there's 200 grain Inceptor ARX. I like how that sounds, .50 caliber AR pistol! Why settle for a BFR when you can get a BFAR? ;D

Don't think "AR pistol".
Those are asinine and fairly useless.
Think "Modern Trapper carbine"      ;D
Title: Re: AR possibilities
Post by: Big Frank on May 10, 2020, 10:10:59 AM
I mostly agree, and I would like a short carbine much mo' betta than an AR pistol. I think all of the SBR and SBS laws should be struck from the books. All of the 10-12ish" Auto & Burglar shot pistols, 12" and 15" Marble Game Getters, 12, 14 and 15" Winchester trapper models (Special Short Carbines if you want to get technical about it), H & R Handy Guns, etc. were outlawed for no good reason. I read that the 18" Marble Game Getter was re-legalized 5 years later, even though it was too short to be a shotgun or a rifle. None of these guns were "the preferred weapon of criminals" as the antis like to say, any more than SBRs are today. But the ATF says wallet holsters are AOWs too, so don't expect them to relax their interpretation of the law. The law has to change beyond their interpretation of it.

Too bad I can't buy a newly manufactured 12" Game Getter. Wikipedia says, A third production model is currently produced by Marble Arms. It is similar in appearance to the Model 1908 and features a .22 LR rifle barrel over a .410-bore shotgun barrel. The only barrel length offered is 18½". But I can't find it anywhere. Me and Teddy Roosevelt used to have solid brass Marble compasses. :) I didn't know how popular their equipment was outside of Michigan, with the U.S. Army, British army, etc. After 40+ years I still have my match safe and it will definitely outlast me. I bought one of their slot fillers for my 10/22 from Brownells when I took the rear sight off. They still make sights, lots of tang sights, a full buckhorn, and even a tritium bead for shotguns. The last one's new to me. I'll have to look some more to see what else I didn't know about besides that and the 28 patents they had. I thought they quit making knives but they're on a separate site. And I see over 200 models at SMKW, including a version of the #3 safety axe.

Check out the reproduction V-42 stiletto. A good dagger and an AR carbine could get you out of some bad situations. Maybe keep you out out some too. Unfortunately I'm not allowed to carry a double edge knife of any length in Michigan. I might accidentally hurt someone. It's considered a concealed weapon and there is no concealed weapons permit to possibly get, just a pistol permit. If I could, a lot of the time I'd carry a dagger, dirk, hunting knife, or a regular knife that other people EDC. The township next door has a law banning blades longer than 3" and there are times I could use something bigger than a jackknife. A 4-5" blade would be really handy but I'd carry one of my big knives too if I could.

I'm replying as I read,
There was a very GOOD reason for NFA limiting all fire arms to 18 inch barrels.
They intended to outlaw pistols by not mentioning them then requiring the $200 dollar tax on them.
It's why I'm so fed up with these blowhards gassing about "their rights".
If they really had any balls the lynching's and shooting would have started 70 years ago when the communist mot#$rfu&@ers made their first move.

I carry a 4inch Cold Steel Ti Lite.
It's an assisted opening stilleto blade , perfect for breaking down boxes and punching vent holes in coffee lids. 
Man has to have his priorities.    ;D
NH doesn't restrict knives at all, Pen knife or Claymore, it's all the same   ;D

Post by: Big Frank on May 10, 2020, 04:03:35 PM
They didn't have a good reason to outlaw pistols either, but the anti-gun bureaucrats will outlaw whatever they can get away with. I've seen TiLites that weren't assisted opening and almost bought one several years ago. The titanium versions were priced kind of high but when they came out with some kind of plastic fantastic handles for a lower price I was tempted again. The weird thing about our knife laws is I can legally carry an automatic knife, with a single edge blade half the length of a dollar bill, but I never heard anything about whether assisted opening knives are legal or not. I read what I could find about it in the state laws about it, which was nothing at all. No mention of assisted opening before or after they finally decided switchblades are just knives and don't need to be banned anymore. With my luck, if I bought an assisted opening knife it would be illegal. The laws never made sense before and I don't expect them to start now.

just re-barreled a spare PSA 9mm lower with a 7 1/2" 9mm upper for my next evolution of a PDW for the car... currently a 10.5 fixed sight tower/carry handle rear sight 5.56...but just an 8 1/2" KAK tube with rubber end cap, no blade or brace... I'd like to greatly reduce the muzzle blast...the 9mm will have the same tube... will look at the Ruger 9mm PC Charger if they ever come back in stock locally.. they have a 1913 rail on the rear for a folding brace, but internal recoil springs so can be shot with stock folded, as well as the PSA AK-V 9mm

I may have the ultimate least expensive answer with the Recover Tactical 20/20 brace that is on the way... will let you know... Les

I'm awaiting delivery of a TNW Aero Survival pistol from Bud's.
I went with 10 mm because people aren't the only things that need shooting.
I don't believe 9mm, or 45 are enough for dumpster bears and the like.
I was thinking modern version of the model 92 Trapper .
Considering that I also carry a compact Witness in 10 mm I don't expect noise and blast to be much from a double length barrel.

I was grocery shopping in the suburbs for some things I couldn't get at the store down the road Sunday. Suddenly the pedal went right down to the floor when I hit the brakes, and I left all my brake fluid ~11 miles from home. I'll take my truck to the dealer next week to get it fixed, and I'm not getting that Deadfoot Arms side-folder until I get the bill for it. I need to re-figure my budget and see if I still have the money for it. I think I will.

What barrel length on the Aero 10mm Tom? I'm sure the extra length will give your ammo a boost even if it's just a few inches longer.
Title: Re: AR possibilities
Post by: tombogan03884 on May 22, 2020, 07:39:47 AM
Over all it's about 24 inches, the barrel is only 8 1/2 of it.
It actually is just about right , it's just long enough that I don't worry about muzzling my support hand.
If I assemble a 9mm I will use strictly AR components though, this is definitely a civilian design with JC clips and small pins.

anecdote... a good friend and USPSA tech-junkie built a blow back 9x25 (10mm necked to 9mm) early on in the PCC evolution... he was shooting a 106 grain bullet at over 2200fps out of the MecTech conversion.. the cartridges would go in the magazine as a bottle neck, and come out of the ejection port as straight wall
Title: Re: AR possibilities
Post by: Big Frank on June 12, 2020, 11:13:13 PM
It sounds like he needed to hollow out the bolt and fit it with a piece of tungsten to give it more mass. Either that or see if Home Depot had some stronger springs.  ;)

That's why HK uses a fluted chamber. It's the only way they can get their basically blowback rifles to extract.
Title: Re: AR possibilities
Post by: Big Frank on June 19, 2020, 10:09:12 PM
I never had anything with a fluted chamber. I think I know how they work but I could be wrong. I think a fluted chamber would make what les snyder was talking about even worse. It seems to me that when the case extracts, the neck starts expanding as it's crossing the shoulder of the chamber and keeps expanding up to body diameter. Wouldn't a fluted chamber leaking gas between the chamber and case offer less resistance, speeding up the extraction that's already too fast? I know blowback firearms need a heavier bolt and/or stiffer springs to handle more powerful cartridges, like in a a grease gun vs. a 10/22. And you need the right balance of bolt weight and spring tension/compression. I think that's about all there is to it. I can't think of any blowback operated guns that come from the factory chambered for bottleneck cases, just straight-wall pistol cases and and WSL rifle calibers. Maybe fear of the cases splitting open when the neck expands is why.

I haven't seen the inside of mine in years but IIRC the Mech-Tech CCU has 2 springs that stretch, rather than compress under recoil like most blowback guns. Like the screen door springs our WWII-era barracks had on North Fort Polk in the early '80s.
Title: Re: AR possibilities
Post by: tombogan03884 on June 20, 2020, 08:41:24 AM
The fluted chamber creates a cushion of pressure out side the casing to prevent it from sticking .
I suspect it also bleeds off some of the excess pressure . It's a work around to make a poor design function.
You could make a pure blow back 30 - 06 but you would need a 27 Lb bolt.
The reason you don't see blow back in bottle neck cartridges is because the available ones now are to high powered for safe blow back operation.
7.62 X 25 was a SMG round and .357 Sig was both to potent and never popular enough to be worth the investment.

I have an ar in 9x25 dillion that is just blow back.  I cant telk you the number of springs i destroyed getting it to run.   Its not 100% and i doubt i would ever get it to be so, but its just a tinker toy.

Just before i built it i did a google search to see if any one else had done it.... what did i find?   My posts on here asking if any one ever had about 8 years prior.     Now somethibg like a roller delay might work, but now you are talking a different gun altogether.   I tried drill out some spots on the bolt carrier and adding some tungsten, but it just did not work.

I think Les Snyder will have some suggestions here .
From what you said about trashing springs I'm ASS U Me ing  (  :D  ) That the bolt is slamming back to hard .
Try ADDING weight to the bolt so getting it moving takes more energy.
Another thing is sometimes they use heavier mag springs so the feed keeps up with the bolt travel speed.
I don't know about the chambering, but that CMMG radial blowback upper may help.
Title: Re: AR possibilities
Post by: TAB on June 20, 2020, 12:03:34 PM
No, the prob was i was using way to heavy of a spring and would cut coils til i found one that worked.  Between that and adding/ subtracting bolt wieghs i think i went thru about 50 springs.   I even tried doubling them for a while.  It was one of those things if i had to do over again i would have a custom bolt made and tried using the gas system.

my first dive into the PCC pool was with a MechTech Glock format...the extension spring (think screen door) was immediately identified as a problem, as I was looking to produce the lightest recoiling carbine possible... I looked hard at a Granger catalog but just couldn't find what I was looking for, in addition to one of the pistol lowers had a tolerance problem, and would go full auto... I didn't even get a chance to run some cartridges across the chronograph...historical note... I did shoot PCC division for a little over a year with a blow back 9mm... using an NFA lower and NFA bolt with a 6.2oz rifle buffer and rifle length AR buffer tube and spring... I then switched to the CMMG radially delayed bolt..


a half dozen years ago I purchased a 16" pencil barrel, can't remember the manufacture... it did not produce the accuracy that I was looking for... with the better pencil barrels now available, and as I have a couple of spare uppers, I may look at a light weight carbine for a project... re:  AR pistols, Tom has seen what I use for a buffer tube for my AR pistols... I think they are the quickest handling of any of my ARs, and would be a tough call not to grab one for any civil unrest ...  if I lived where auto loading rifles were not legal, a 16" model 92 (not 94) in .357 mag would be my pick

For a lightweight build I made about the same time (14-1/2" bbl) I picked up the lightest I could find which was at Spike's Tactical.  It is a forged barrel and is really accurate...I don't know what another 1-1/2" would do to the accuracy but I suspect not much.  Come to find out...it was produced by FN.  Just my 2 pennies....

I couldn't remember if they had a pair of extension springs or just a single spring, but yeah, they're just like those screen door springs. They pull instead of push which is a little unusual for firearms. I've seen a whole lot of guns with compression springs and the occasional helical torsion spring, but not many extension springs. There are some in the trigger groups of a few guns. I think my Remington 12 gauge has one for the shell lifter but I may be thinking of a different gun. That one's overdue for a cleaning if I ever get my front Fire Sight on. I think I have everything else done and have to detail clean it.

The AR-15 ejection port cover spring was one of the first torsion springs that came to mind but it seems like almost all gun springs are compression springs. Not much of anything else that I know of in commercial firearms, but I don't know much about the innards of most of them. Back in the army someone brought an M240 in that was messed up. The buffer spring is a stack of Belleville washers that are supposed to be stacked like ()()()() and someone took the buffer assembly apart and put them all back in like )))))))). They took up less than half the space inside the buffer tube and it didn't work. So it battered the hell out of the bottom of the hole when the piston drove the bolt and operating rod assembly into it where there should have been a cap sticking out with a stiff spring (the washers) behind it. I thought they were called bell washers but looked them up before and they're Belleville washers. They look just like heavy duty flat washers except they aren't flat.

I downloaded a picture of a MechTech CCU recoil spring from their site. It's just like a screen door spring like I said. They sell replacement springs but I don't know how to tell when my spring needs to be replaced. That's the only reason I didn't buy one with my other stuff. If it was a compression spring I could measure it in a relaxed state and see how long it is. Now maybe I can measure it with a certain amount of weight hanging on it to see how much it stretches. Or just wait and see if the bolt beats up the rubber buffer until it causes some damage. I'll have to ask about it.

latest iteration of a game gun... I've been shooting Steel Challenge matches for most of the last year... I don't have to run, just stand and shoot except for one standardized course... I built a 10/22 on a BRN22 receiver and PMACA chassis with an AR grip and adjustable stock... not pleased with the reliability, probably traceable to the rotary mags (that I thought were bulletproof)

currently shooting a 10 1/2" CMMG dedicated upper and conversion .22lr bolt for my registered SBR... it is working very well for me... quick handling, uses a good AR trigger, cheek weld SOCOM stock and Hogue hand grip... the conversion unit is very easy to remove for cleaning which provides good access to cleaning the chamber... the extractor is a first degree lever... polymer feel lip 25 round mags allow you to shoot with only one interruption to you shot string... topped with a Holosun 510 large format dot

for a pistol : a Ruger MKIV 22/45 lite... I paid extra for the light weight, but decided afterwards that I liked the way a slightly heavier nose would swing... my cousin built me a muzzle weight... added Striplin/Tandemkross thumb rests and grip, topped with a Holosun 510... after 35 years of shooting fixed sighted pistols, getting used to the dot for quick target acquisition is still a learning curve...I'm hoping the .22 ammo will get in the pipeline by the end of the year... I think I have enough squirreled away until then regards Les

Email it to yourself and reduce the file size if it asks.  Then, try and repost.

While not a "Photoshop" I've found IrFanView to be a very useful Windows utility for resizing and renaming pictures.  It can do some basics like cropping, but it's main feature is being able to do a batch of pictures at once.

I too have two 22/45 Lites for Steel or Rimfire Challenge.  One with red dot and one with iron sights.  Doing the 10/22 thing for rifle though.

Here's an "AR possibility" .
With this 3D printer I am currently printing a functioning Luger, works on pen springs.
It won't shoot, but it's a Luger, and it won't cost $2K.
I've got guns that shoot already.
But I want ones that are cool .
My point is this, AR receiver plans, drill guides for 80%'s those are all over the place, but where are the rest of the parts ?
I want a M 203, but I only want to pay about $25 . ;D
The sky, and my print bed size, are the limit !   ;D

Can anyone tell me why people even bother to put bot's out there? Phishing? I don't understand what someone gains by unleashing bots.
