Easy peasy
Broke the end off my last gun just from shooting it so my new gun I put this reinforcement in and it seems much more stable. Easy to put in and I hope it keeps the bands from breaking the end of my gun again!

Hasn't failed me yet
Dunno if it is actually helping, but makes me feel better about having 3 bands loaded for extended period.
