The trigger and bayonet problem are easily fixable . I can 86 the muzzle brake and find a bayonet for it , and I can either get used to the trigger or get it worked on myself , but I broke it all down and yes , it ' s serial matching and yes , he drilled the damn receiver . I consider it a steal . He basically killed any resale value this thing had with the mount probably why he let it go so cheap but if I have nothing to lose then I ' ll have my fun playing with it . I agree about original being the best , but Timbersmith let ' s me keep the look and feel of the wood stock while knocking 2 items off the 922 r count . If I swap the piston and the trigger I can basically do whatever I want to it from that point .
