Case slippage or failures to extract? This is your ticket. Remove your BCG, pull the bolt, drift the extractor pin and replace your old springs and post with this setup. BCM kit is the best you will find. Spring is perfect fit with the post insert. Rubber butt hole is an upgrade and may not be needed but if you do use it, it will be a tight fit on the case rim. Reassemble in reverse order and your good to go. Keep spares because your butter finger teammate will lose his rig in the sand. Just sayin'. Peace brothers.

BCM always the best

Works perfectly!!
Best $4.95 I’ve ever spent, my rifle runs phenomenal now!!
Bought a new bolt carrier.
Extractor spring was practically flat, jammed every time I tried it. Ordered BCM extractor spring kit. No more problems. Make sure you keep some spares could make all the difference.
