am i completely retarded for thinking a 22" FAL barreled reciever could be chucked in a 4 jaw or something, indicated in and cut crowned and threaded without having to remove the barrel from the reciever? my local guy says he cant do that, am i just way off? i am not a gunsmith but do have moderate machining experience with lathes and mills and didnt figure this was that hard a task. school me please guys.
