Has the rifle been cleaned and lubed correctly (CLP) before being fired (read the chamber scrubbed with a chamber brush by hand, and any copper solvent completely removed from the bore/chamber and left in a dry state)? http://www.ar15.com/forums/topic.html?b=3&f=7&t=203988 Also, what LC ammo? |

The rifle/barrel is packed with assembley grease (maybe even a little shop floor/bench grit), and was the problem at hand. Check out the link I posted, and do a detail cleaning on the weapon, including pulling the buffer and recoil spring to clean and CLP the receiver extension parts as well. |
