Always good to keep backup BCG parts around. Have seen low quality gas keys get all kinds of wear. For the price, wont find better quality imo

Had a cheap, poorly staked bcg and the key bolts backed out. Caused the key to take an impact when firing and bent. Picked this up to replace it. Did the job well.

Fit right on my BCM carrier after I had a malfunction that bent my old one. Feels more robust too.
