| Any feedback on how it shoots? Been running 118lr and it shoots really good, don't know how the Federal compares. |

Quoted: Short stroking issues. My OBR is extremely accurate but a bit of a picky eater for 100% reliability. I am having the exact same issues. I called Larue and they are sending me a new BCG. Hopefully it will solve the issue. I shot around 70rds of 168gr FGMM and couldn't shoot more than 3-5 shots before the bolt failed to pick up a new round from the mag. It is frustrating spending so much money on a rifle and it not working properly. I also had 3-4 jams where the bullet got lodged between the bolt and feed ramp during those initial 70rds. This was with both the factory Larue mags and brand new Pmags.  |

What barrel length? Sounds exactly like the problems I have. I have simply resorted to finding a few rounds it feeds well, and I had the intentions of doing a lot more testing to get a statistically significant sample group before I contacted large again, but I have been short on money the last few months. I can definitely relate to your initial disappointment. Oddly enough, the 168 FGMM is one of the rounds that my OBR feeds quite regularly. |

Try a lighter recoil spring or a lighter buffer.... I had that issue on a 6.8 and removing the hydraulic buffer and installing a standard buffer took care of the issue. The short stroking only happened on that rifle with "New" magazines, I had no problems with my older magazines, just the newer ones with stiffer springs.
Also consider using the 118LR or 147gr NATO, it might be a little higher pressure than the FGMM. That little bit of extra pressure might be enough to eliminate your short stroking/feeding issue until you get the rifle broken in.... |

I don't want to hijack this thread anymore, but I've BTDT with regards to buffers and ammo types. If you want to know more PM me or I can bump my old thread. |

That's ok, sounds like you're totally on top of it.... I think I remember your old thread.... Good luck with your rifle!!!!!! |
