First Build - Left Hand AR 10.5" Pistol - Pics now added

**MarkB1** · 03-20-14, 20:53

Here you go. This is my first build. I have room to make some improvements later as time and cash allow.

Before I do anything I MUST thank ADCO Firearms (adcofirearms.com) for their help in removing the barrel and cutting, crowning and threading the barrel. I simply could not have done this without their help. Their work was of very high quality!

After much reading and comments and suggestions from members I have decided to go with a H2 buffer instead of the standard buffer that came with the buffer tube.

Here are the parts.

Stag 3HL 5.56mm upper, 1/9 twist cut to 10.5”
Troy Claymore muzzle brake
McFarland One Piece Gas Ring
Yankee Hill gas block folding front sight
Yankee Hill folding rear sight
Bushnell First Strike red dot sight
Guntec carbine 4-rail hand guard
ERGO hand guard ladder rail covers
Magpul AFG grip

Stag lower receiver with left hand safety
AR15 pistol buffer tube set designed for the SB15 from The Global Sportsman
Stag H2 Buffer
Sig SB15 pistol brace
KNS Gen2 Mod2 trigger group pins
Norgon Ambi-catch mag release
Oversized trigger guard by Dead On Arms
Bravo Company Mod 1 pistol grip
Magpul AFG Grip
Magpul MWF Magwell grip

If you notice the front sight is on backwards so it will clear the forearm. If I put it on normally, the sight hits the forearm and does not go all the way down.
The Bushnell First Strike red dot sight works find. It sits above the folded sights and below the sight line of the upright sights.

This is one FUN gun to hold. I can only imagine how it will be when I actually fire it.

I have put a Troy Claymore muzzle brake on the pistol. In case I should forget how, the Claymore comes with instructions:

I'm looking forward to getting to the range with this pistol.

I had my burris fast fire mounted like that, but when actually shooting it made me scrunch down to far and was uncomfortable. Primary arms has cheap yhm risers if you run into the same problem.
Now you just need to build a 300 BO version, you already have the carbine buffer.

Were you able to get co-witness with the riser? I see Primary has the 3 slot riser that raises 1/2" for $16. Thanks for the tip.

Yes it did. absolute.
At first I liked being able to flip the sights up and they looked out completly over the top of the RDS. But like i said in actual shooting it proved to be less than acceptable.
Now with the 1/2" riser it's easy to shoot and co-witness is perfect.
I also like your linear comp, I have not tried the troy version, but it should work like all the rest. Still going to have considerable blast outta that little noise maker.

Thanks, I checked my stuff and found a GG&G 1/2" riser I can use. Sometimes you get lucky.

Here's another comp you can consider. I have one on my LH Gunsite rifle and it works fine.

This is the smooth model that will be available mid-April.

Does the magwell grip not turn this 'pistol' into an AOW?

Neither the MWG magwell grip nor the AFG forearm grip make the pistol a SBR or a AOW. It's still a pistol. There are ATF letters about them out there. You can search for them.

I knew the AFG was cool, just not about the MWG. Thanks for info.
