I have a LWRC M6A2, with a Geissele 4.5lb trigger installed. Today I went shooting with it, without any problems. After I fired a few rounds, I made my weapon safe (dropped mag / ejected round) and went downrange to check the targets. I did this four or five times.
The Problem: I noticed the rounds that I ejected had very light primer strikes. These were rounds that fed up into the chamber, that I opted not to fire. Does anyone know what caused this… more importantly, how to fix it? It is almost like the firing pin is bouncing forward. Ideas? |

It happens in all semi auto rifle with a floating firing pin. When the bolt closes the firing pin goes forward hard enough to mark, but not detonate, the primer. Yep, and don't panic, its not like the FP is slamming into the primer forward full tilt. If you look at the B/C (back side of the carrier where the tail of the bolt comes out the back of the receiver only when the bolt has locked up, and until then, the back of the carrier blocking the FP from going any farther forward to protrude when the bolt is not locked up), you will notice that the FP can fully protrude out the bolt face after the bolt has locked up. But on the same note, not wise to keep loading the same unfired round over and over again, since give enough light strikes, such could set the primer off. |

This one range I shoot at will not let you bring your weapon down range. Otherwise, I would not keep unloading it. Thanks again. |

Regardless of bringing the gun down range the more important thing is not having it loaded with a bunch of other people around. Holstered pistol is a little different than a slung rifle. |

Don't ever go down range with a loaded weapon on the bench..are ya nuts???? And if you finish your mags or only load 5 rounds or so you will shoot it dry.. EDIT Spotting scopes and binos are cheap. buy one so you don't have to go down range.. |
