I had a long boring post about my recent trials and travails trying to get an AR-15 barrel off the receiver.
I'll save you the time.
Let me just give a great big thanks to James over at Hot Rod Arms in Tyler Texas. He has mad 1337 skillz with black rifles, a shop with gunsmith area in the back, and accessories. They sell to Law Enforcement, as well as regular guys (and gals). Oh, and he's a class III dealer.
The prices are reasonable.
The staff was great.
