Like a retard, I used my $235 buttstock to smash something. Both the lugs on the butt stock that engage the buffer tube sheared off. There is some light damage to the buffer tube. Also, the pin that holds the locking tab has cracked out of the adjust lever since it was locked in P7 at the time. It won't hold the recoil of a 55gr .223 now. I have some pictures, but basically I need the lever that you pull to adjust the stock and instructions on how to replace it. Is this something I can do or do I need to send in the whole buttstock?
