    Have rock River AR10. Having issues with bolt after shooting M118 7.62 rounds. Bolt lock forward after about 30 rounds shot through it, dry fires on live round, have to bump stock to release bolt. round removed but bolt locks forward again and same dry fire. After removing bolt found key and firing pin hard to remove. removed and inspected, no issues found, cleaned and reassembled functions good. No issues with win .308 seems only with the 7.62 NATO rounds does this happen. Is it known not to use this ammo in this carbine? Hearing conflicting information on this heard for AR-10 NATO or 308 is fine but heard not the other way? Which is it?
