Hi Everyone,

I picked up a lightly-used AR-15 a week ago. I finally had a chance to try it out and it seems to be short stroking and not rechambering a round properly. I really like the rifle and don't want to make it worse by working on it myself. can anyone recommend a good gunsmith that specializes in AR's?

While I don't know of any good AR gunsmiths in the Atlanta area I can give a couple of suggestions. (I've built a few AR's myself :supergrin: )

First get some other factory loaded ammunition than what you were using and try that. Ammo such as Winchester white box 55gr FMJ would be fine. If that is what you were using any other brand name 55gr FMJ will work. You are trying to eliminate the ammunition as the potential cause of the problem

If the ammo change does not fix it. Look down into the opening of the bolt carrier key. Has someone jammed a Q-Tip down there and broken off a piece. Running a pipe cleaner down there and into the bolt carrier will tell if there is any obstruction. Check the bolt carrier key to make sure it is staked tightly on the bolt carrier. Check the gas rings on the bolt. There should be 3 total and the opening on them should *not* be all lined up. I like to stagger the ring openings into third way around the bolt.

Next check the buffer, buffer tube, and buffer spring for any damage or obstructions.

Check the front of the gas tube to make sure it is still staked securely into the front sight assembly. Make sure there are no dents in the gas tube and that it is not damaged in some other way.

Also be sure to look at the area where the gas tube goes into the bolt carrier key - looking for damage and obstructions.

If you are near the Villa Rica / Carrollton area I'd be happy to take a look at it for you. We can test fire it out at a private range just north of Carrollton on Hwy 27.

Regards,
Rob

I put 10 rounds of Fiocchi 55gr and 4x that must Federal 55gr walmart special through it, so the ammo was at least reasonable quality.

I ended up taking this to David's Gun Room in Norcross. Their specialist confirmed my suspicion that the former owner buggered up the aftermarket gas block.

I'm taking it up to the Red Hill MG shoot this weekend to see if the problem really has been fixed. Hopefully they won't mind me showing up with my little semi-auto poodle shooter... :-)

Well, after the gunsmith fixed it and test fired it, it took all of one magazine for the short stroking to come back. I think I'm going to have the gas block replaced - I think it's the cheap $35 chinese thing they sell at Cheaper Than Dirt - I might get a Yankee Hill replacement.

You show your location as N.E Atlanta you could run up I-85 to Braselton and
Talk to Mark with Polite Society inc. (678) 234-9545

They are great with AR's and also can set you up with a "can" (and help in the paperwork) if you are leaning in that direction.

I wouldn't mind a "can", but my first priority is an AR that actually functions. :-)

Not long after my last post I had the good folks at David's Gun Room in Norcross put a YHM steel 4 rail gas block on my HBAR in place of the cheap Al thing that came with the rifle. Nice people, good service and excellent 'smith services.

I finally had a chance to chance to try it out. Or rather, my father took out to the range for me and put a few hundred rounds through it. Apparently it still doesn't like Wolf military classic but cycled just fine with everything else (Federal, Fiocchi, Silver Bear, PMC, etc). So, I'm a happy camper and have an AR that works better now.

Next step is to add the can.
