gsp

I just finished 2 genesis lowers and had problems with bolt stop on both. Ended up opening the hole on the bolt stop itself at the bottom of the hole. also had to grind some off the bottom were the dentent hits for more lift to engage the bolt

Thanks

I recently bought a used cmmg mk3 that also had loose handguard screws and barrel nut. I used a strap wrench to re-tighten the barrel nut and low srength loctite for the other screws. Havent had a chance to shoot it yet.
