I have a RRA LAR-8, brand new (120 rnds through it so far) and I'm having some pretty significant feed problems. Every 2-4 rounds the weapon will not go all the way back into battery after it ejects the spent casing. It stays open somewhere from 1/16" to 1/4". I can eject the misfed round by charging the weapon and it feeds the next round fine, also, when releasing the bolt from the open position it chambers fine. If I reload the misfed round into the magazine and continue firing the round feeds fine. I have never had any ejection problems.
Another problem which happened in the last 40 rounds or so: every 2-4 rounds the firing pin would strike the primer but not pentrate deep enough to ignite it. There would be a small dimple in the primer but it would not fire. When I reloaded and rechambered the round it fired fine.
I broke down and cleaned the rifle before the 1st shot and after the first 60th round. The only thing that I didnt clean was the extractor because I couldnt get the pin out. I have a feeling that the second problem could be caused by a tight or dirty extractor. Any help here would be great, thanks in advance.
