Kirk Posted October 1, 2017 Report Share Posted October 1, 2017 AR 10 in 308 having feeding issues with mag installed. Bolt slows about half speed with ammo in mag, no ammo it closes normal speed. Closes normal without mag. Cycles fine when single loading, locks bolt open like it should. This is driving me crazy trying to figure this out. I've never built an AR10 but have built 9 AR15's with no problems. Thanks in advance Quote Link to comment Share on other sites More sharing options...

bfoosh006 Posted October 5, 2017 Report Share Posted October 5, 2017 More info as well , please. My PSA PA10 GenII does this with Lancer Mags ( ever so slightly ) But functions perfect with Magpuls and D&H mags. Quote Link to comment Share on other sites More sharing options...
