i got the trigger, disconnecter and gas piston for it and as i understood it the firebird handguard worked as a 922r complient part, so i think im sitting on the happy median of being on the ok side of things, thanks for the info on the firebird lower i will try nanci i just got the gun running at about 95persent so this was a little depressing so i will just transfer everthing from the old lower to the new one if i can get one from firebird.
