Does the lrbho work with a bone stock fm9 with 3" barrel? Also, which buffer weight should I use? Expert Answer

The JP Enterprises EnhancedBolt 9mm AR Bolt Carrier Group Kit should work fine with an FM9. I recommend using the JPBC-9SL-5H2SS or JPBC-9SL-SP5H2SS model.

So let’s talk about the elephant in the room. Your LRBHO only works on certain uppers with this bolt. On my set up it doesn’t. Rather frustrating since that’s why I spent more money on the “enhanced bolt”. This set up does run smooth. You can definit...
