i have a psa ar15 it is not cycling correctly it will fire a round and the bolt does not move i can charge another round manually (its smooth as if nothing is blocking or grinding)and it does the same thing its properly lubed and i broke down the bolt carrier group and lubed and cleaned it my first guess would be the gas line clogged but seems unlikely because it has less than 300 rounds through it love to get some opinions mags being used are pmags and ammo is pmc brass and ga arms both with the same effect any help would be appreciated thanks!!
