Not sure of the spelling but I was wondering if anyone had tried the MecTec conversion where you use your pistol frame on their carbine conversion top end? If so is it worth it? Does it work as advertised? Any other input would be helpful.
Thanks,
Richard

I have a MechTech CCU on a Para-Ordnance pistol and haven't shot it much but didn't have any issues. If anyone made a camp carbine type of rifle that took double column Para mags I would have bought that instead. One thing bothers me about it. I have the collapsible AR type stock and it's only held on by one skinny screw. It seems like it would be easy to break but they may have changed it. For that reason I'd rather have a designated pistol caliber carbine if it uses mags I already have. http://mechtechsys.com/

Richard... I have a small frame Glock version in 9mm.... I like to tinker with my guns, and there is not a lot of options for fine tuning the action.. the bolt is a little heavier than my dedicated 9mm AR9 PCC bolt + buffer and the recoil spring is an extension (screen door) spring... works well with factory ammo, but mine won't run on loads less than about 150 power factor...for a do-over, I'd choose the self contained firing system of my high cap Para lower sitting in the safe, and buy 9mm mags for it.... accuracy is good, and is fun to shoot... if you are thinking of just occasional shooting, it gets you into the PCC game for a reasonable investment....the AR platform is more familiar to me, so I invested in building an AR9 and the MT is probably going to be up for sale....I haven't shot a pistol for the last 6 months for USPSA matches.... Florida State match in 2 weeks....if you have specific questions, please post... regards

I upgraded to a dedicated AR9, using New Frontier Armory billet lower... it is a new learning curve

JF and Les, thanks for the input. Just thinking out loud so to speak. $$$ is kinda tight right now and I think the MT would be cheaper that a dedicated 9 AR. Don't have one in 223 so you can see my dilemma.

While a dedicated 9mm ar patern carbine might be pricey you may want to look at some of, the other option as well. Don't forget to take a look at the sub2000 for glock mag patern if you have a glock already. Another one to check out is the JustRight carbine. I believe that both offer options for Glock and Beretta mag patterns, not sure of any others. Someone else may know more.
I love my Lone Wolf 9mm ar patern but it certainly is not for a budget plan.
-
Richard... my AR9 was under $800 without the sight..

I took a look at their website and the collapsible stock they have now is different from mine. It looks like it uses a standard M4 stock with an adapter mounted to the back of the housing. It doesn't show what holds the adapter on so it may or may not have a single screw like mine. Hopefully they use a larger diameter that's harder to break.

Opening up an old thread. Has anyone with a MecTec chronoed ammo to see how much velocity is gained over the same ammo thru a pistol?

Not me, but I've seen where people have chronoed a pistol and a different model of carbine. I don't remember what the percentage of velocity increase was, but with some ammo it worked out to roughly 1/3 more muzzle energy. I think I was only looking at .45 ACP since that's what I have.
All I know is that +P ammo from my MechTech hits pretty hard. One time I had some 185 grain +P flat tipped FMJ ammo that I think Winchester originally loaded for the SEAL teams. I filled an empty pop can up with water and when I shot it the can ended up in 2 pieces. I was expecting a big hole, but not 2 separate pieces. Hollow points should be very effective.

There are 5 different calibers available depending on what pistol frame you have. +P ammo is acceptable but +P+ is not. The M1911 version is available in .460 Rowland. You can use most any modern 1911 frame with it except those made by IAI in the Philippines, AMT, Auto Ordnance, and Charles Daly. Clark Custom used to recommend that you don't use any of those or original G.I. pistols. They made conversions for pistols without a ramped barrel. I have a ramped barrel on my Para Ordnance .45 and have to use the Para Block to fill the space in the frame and act as a feed ramp. It would be a weak spot if I did that with a .460 Rowland but doesn't hurt anything with .45 ACP.
-
Ellis... not with a MechTech but I shoot the same load in my G34 as my 16" PCC... a 3.6 load of WSF and 135 Bayou coated gives me a 130pf with the pistol, and 146pf with the 9mm carbine... about 120fps difference
-
I totally missed this thread last year. Too much work. However, I'm glad it was revised. I didn't know about these conversions per se'. Now, I see they make a 1911 frame model for 10MM. Sounds like something I'll need to check in too.

If I'm not mistaken they've made 10mm 1911 and Glock conversions for a long time. AFAIK the XD conversions have only been around a few years, but I don't keep up with things like that. There are no 10mm XD conversions.
As far as velocity is concerned, Ballistics By The Inch has a lot of loads listed for all 5 calibers. Some are barely any faster from a 16" barrel than a 4.5 or 5" and some are around 300 FPS faster. http://ballisticsbytheinch.com/index.html

I have a Kimber Eclipse II in 10MM. I wonder about loading with rifle powder to use the extra barrel length???

If you can find a load published by a reputable source go for it.

Rastus... I've been fooling with a 9mm blow back carbine for a while, and the blow back design is a different animal...I don't think I'd try to hot rod it as you would a locked breech firearm.. a friend chambered a MecTec in 9x25 (10mm case necked to 9mm) and got straight wall 10mm brass ejected... the game players are loading light bullets with VitaVuory triple based powders...
Rudy Koester at Macon Armory makes a locked breech DI carbine, I believe in 10mm

It would be interesting to know what caliber MechTech they started with. It seems like there would be a difference in spring strength and/or bolt weight between a 9mm and a .460 Rowland and calibers in between. If the conversions can handle .460 they should be able to handle 9x25 too.
-
Jumbo... this was several years ago... they started with a 9mm barrel and ran a 9x25 reamer in it

I can see why there would be a problem with it operating at a higher pressure and double the energy it was designed for. You can't change things that much on a blow-back and expect it to work right. If the bolt had a large chunk of tungsten in it, or the recoil spring was twice as strong it might have worked.
-
Well, I think I'll call them this week and find out what they can do for 10MM. I want to shoot full powered ammo and likely something from DoubleTap which is pretty hot.
Now, if I could just find an MP5 in 10MM....hmmm...naw, as rare as hen's teeth.

They make a 10mm CCU for 1911s and one for Glock 20s and 40s. If you get the Glock version you need to buy a feed ramp for it. It comes in 2 sizes so you just tell them what model you want it for and they'll get you the right one. If you get a 1911 version with a ramped barrel like my Para-Ordnance you need a Para Block that only comes in one size. If your frame isn't milled for a ramped barrel there nothing extra you need to buy.
On the Glock page it says: Factory Loaded Ammunition Only. Mech Tech recommends only using good quality factory loaded ammunition in the CCU which meets SAAMI, CIP or NATO standards. The CCU is a blowback operated action and is capable of safely firing ammunition up to +P. DO NOT USE +P+ or ‘hotter’ loads.
The 1911 page says: Factory Loaded Ammunition Only. MechTech recommends only using good quality factory loaded ammunition in the CCU. The CCU is a blowback operated action and is capable of safely firing ammunition up to +P. DO NOT USE +P+ or ‘hotter’ loads.
And the XD page says: Factory Loaded Ammunition Only. Mech Tech recommends only using good quality factory loaded ammunition in the CCU which meets SAAMI, CIP or NATO standards. The CCU is a blowback operated action and is capable of safely firing ammunition up to +P. DO NOT USE +P+ or ‘hotter’ loads.
So you can use any ammo that's within SAAMI specs, whether it's +P or not. I haven't seen any 10mm ammo labeled as +P but if I did I would look for something else.

Here's a video from YouTube that wouldn't work when I tried it from another site. They shoot 10mm DoubleTap ammo in a MechTech carbine.

Hi-Point is coming out with a 10mm carbine with a 10-round mag sometime in 2018. https://www.hi-pointfirearms.com/index.html

There's another PCC option this year. Iver Johnson is selling a .45 ACP 1911A1 carbine for $698.00, and a 28-round .45 ACP 1911 drum for $75.00. In the past I've heard that 1911 carbines don't always work very well. I'll be waiting to hear the verdict on these.

Numrich Arms (Gun Parts Corp.) Used to sell that as a kit. Was under $150.00 if I remember correctly.
-
The 1911A1 carbine needs a VFG so there's a good place to hang on with both hands. Without it, I think it would be awkward but not entirely useless. A full length dust cover with a Picatinny rail would be nice.

Years ago, maybe a year or 2 after they came out I bought the 1911 version. While I traded it away later I did enjoy it. It WAS a bit bulky and "chunky" feeling. Heavier than needed, and did not have a fancy finish but it DID work, allowed for mounting an optic, and allowed me to carry my 1911 and have a carbine for backup that did not take up very much room. All in all, I would own it again now, maybe for the clock since that would lighten it up a bit.
