Title: Building a custom AR
Post by: blackwolfe on December 02, 2009, 03:53:37 AM
Seeing KPR's new AR got me thinking.  If you were building up a lower, and then either building or buying an upper, what would you put together?

I'm not sold on the gas pistons yet as there seem to be so many variations out there, so for now I would stick with the conventional gas system.  I like the mid length gas system on a flat top.  Free float tube with not a lot of rails. Hogue grip. Rock River tactical carry handle rear sight and conventional front sight, or maybe a railed gas block with a removable front sight.  I like the Rock River coyote rifle gas block.  Probably a enhanced trigger guard.  Collapsible stock, but nothing fancy.

Hey BW

Like you said, I just built a new AR so I've been thinking about the same thing.  As I mentioned in the other thread, there are a few things I like and put on almost every AR I have. 


I'm with you also...I'm souring on a lot of rails.  Overdone and I don't hang that much on my rifles.  I like the smooth handguards that allow you to put rails only where you want them.  YHM makes a nice one that is about 1/3 the cost of others.

No offense intended!  But it is good stuff.

Magpul MIAD grip with multiple cores
VLTOR stock
flat-top upper
good back-up sights, e.g. ARMS

I agree with KPR on the smooth fore-end - I got a YHM fore-end that has full rails on the top and sides, but a short forward rail on the bottom, with a smooth (parkerized) round shape where the hand goes.

It really depends upon two things.  What you want to do with the rifle and how much you want to spend.  There is such a huge aftermarket parts and accessories industry that many times it comes down to what looks good to you.

I would suggest you look at some of the pictures threads on AR15.com or M4Carbine.net to get an idea of how you may want to build up your AR and what it may look like before you lay out cash on your pet project only to find you don't like how a particular part "looks" on your setup.

I don't really pimp mine out. I just changed grips and put a free float tube on one of them. The other one has a $6 plastic rail on it to hold a foregrip and flashlight. I put a JARD trigger in one and changed a couple other small parts.

Agree with jumbo,.... simple, functional, high speed, low drag, just enough to cover your application.

Less is more. Put the "goodies" in the "guts, nuts, and bolts" and it will be a real keeper.

Im not sure that building is the way to go since prices are so good. Gas piston rifles under 900.00 and a good duty carbine under 700.00. From there you can add on. Depends on how many bells and whistles you want.

Except I got to build it the way I wanted from the get go, versus buy a "good duty carbine" for $700, spend time taking it apart, putting all the new parts on, then either trying to sell them one by one or just putting them in a box.

I didn't build to save money.  I built to get the gun I wanted.  And I can guarantee you the gun I built isn't offered by anyone as a stock item.

I didn't see this thread when I posted mine 5 minutes ago so I'll take mine down and repost here.
I am going to bite the bullet (haha) and build an upper for me, myself and I. I want an upper built off a STAG upper reciever (just like my M&P15) with a 11"-14.5" barrel. Any recommendations on who would offer such a thing or parts there of. And are there any legal issues with the length if I'm building it myself. I am in Ohio so there are no WHACKED out laws here to speak of. My vision is a flat top with free floated barrel 11"-14.5" with quadrail and troy flip sights. Look at the M&P15T but shorter. Any thoughts ideas or suggestions. I know you guys are never short on opinion.

Anything less than a 16" barrel will require you to have a tax stamp. $200 and a whole lot of waiting. You must have the stamp prior to getting the barrel. (Not that you "can't" get the short barrel, it would just be illegal)

FWIW shorter barrels in the AR platform are more prone to failures. They tend to be a lot more picky about the ammo used.

If you really want it, apply for the tax stamp. Don't let FQ scare you with stories of midnight visits from the ATF to check your weapon.  :P

The $200 tax is for Machine guns and Suppressors, If I remember right  the tax on MB's Serbu Shorty 12 ga. was $5 as it is a different classification, (short barreled Shot guns are classed as "Any other weapon") I think, SBR's (short barreled rifles ) are the same $5
But you still have to do all the paperwork first.

Nope. I have 2 friends that built SBR's. It is a class 3 weapon. $200 tax stamp.

 OK, I wasn't sure, but I knew MB said the Serbu was only $5.

Quick search found this. I had never heard of the $5 tax before. Looks like you make some cool stuff for less money.  ;D

Under the National Firearms Act (NFA) it is illegal for a private citizen to possess a sawed-off modern smokeless powder shotgun (a barrel length less than 18 in. or 46 cm and an overall length less than 26 inches) without a tax-stamped permit from the Bureau of Alcohol, Tobacco, Firearms and Explosives, which requires a background check and a $200.00 fee for every transfer.[1] (Short-barreled muzzleloading blackpowder shotguns, in contrast, are not illegal by federal law and require no tax-stamped permit, although they may be illegal under state law.) As with all NFA regulated firearms, a new tax stamp must be purchased before every transfer. Inter-state transfers must be facilitated through a Class III Federal Firearms Licensed (FFL) dealer while intrastate transfers may be between two persons.

Additional restrictions may apply in many other jurisdictions. State and local laws may entirely prohibit civilian possession of short-barrelled shotguns. (These restrictions do not apply to military and police departments.) In addition, some firearm types that would normally be considered to fall into the Short Barrel Shotgun (SBS) category are not legally considered to be a SBS. A shotgun is legally defined as a shoulder mounted firearm that fires shot. Shotguns and shotgun receivers that have never had a buttstock of any type installed are not shotguns, as they cannot be shoulder mounted. Therefore, cutting one of these below the 18" barrel and/or 26" overall length cannot produce a SBS as the firearm was never a shotgun. The Bureau of Alcohol, Tobacco, Firearms & Explosives recognizes these firearms as being a smooth bore handgun which is an Any Other Weapon (AOW). Unlike a SBS, an AOW only carries a $5.00 tax and can be moved interstate without Federal approval. However, to maintain its AOW status, one may generally not have a buttstock (making it a SBS) or a rifled slug barrel (making it a Destructive Device (DD) if the bore is over 0.5"). Both SBS and DD weapons require a $200 transfer tax and prior Federal approval to transport interstate.

Maybe the least of your worries when building a whole new gun, but unless you have very small hands, I'd avoid the Hogue grip you mention.  I'd bought one (thats been laying in a "spare parts box" since day 1) and like the feel, but it's just to small to provide good support if I compare it to the factory grip that came on my DPMS, or even better, the G27 grip I use.  I've tried about every grip I've ever seen for AR's, and while it may not be the "tacticoolest", the CAA G27 wins hands down for comfort and having a good solid feel for me.
