Most Helpful Positive Review Just the BCG out of stock? No problem!
I was pleasantly surprised to see that when I could not get just the FM9 BCG, I was able to, for the same price, get the same BCG but WITH a solid steel buffer and 308 flat wound spring, made for AR9 builds. I've built several AR9's over the years and all but one was with the FM9. They run smooth, seem to be tough, and have a great look via the shell ejection port.

Works good but

by Haunted Bliss, Verified Owner from WI, United States Written on July 21, 2024
Bcg had same issue as another review where spring pin wasn't flush and was mushroomed. Didn't affect function. Cycles fine with endomag without scraping mag. 308 spring had issue with charging and clearance. Very hard to pull charging handle.
Used buffer and regular AR-15 spring and no issues at all. It works so overall worth it.
Pros:
  • Price
Cons:
  • Quality Control
Best Used for:
  • AR 9mm Build
