I have run roughly 400 rounds through my MP10. 200 of outback 168 Sierra match king and 200 of hornady 168 match. Switched to federal 149 XM80C, now I am short stroking (at least I think). Rounds eject, but won't feed. Will an adjustable gas block fix the problem.
Using a Troy lp gas block, magpul mags, PRS, surefire muzzle break, Troy battle TRX 12".
