US Made Parts by Hotbarrel
I'm putting in a plug for hotbarrel, who is a fellow member over at http://www.gunco.net
He makes US pistons out of stainless steel in any size you need, so if you need an AMD, AK-74, '47, Krinkov piston, whatever, he can make it.
He has also made some Galil and FAL pistons, Tantal muzzle brakes, among other things. He always has something going on so if you need a compliance part, you should check with him as his prices are extremely competitive and his quality is outstanding!
Winter 2007: Tantal Brakes: New for me, but not new for HB. He's already made several hundred of these....
October 2007: New VZ-58 muzzle brakes! I sent him some pics and measurements, and he made an awesome copy of the VZ brake. This can be permanently attached to a VZ barrel to make the barrel 17.25" OAL:
Feb 2005: Updated, higher-res pics:
Some of the original runs... many for AK pistols and AKSU builds!
