Most of the cycling issues Ive heard of are from under gassed guns short stroking... Ejecting the empty shell but the bolt doesnt come back far enough to grab the next round out of the magazine so it closes the bolt appearing to be locked and loaded but its actually empty.
Ive fixed a couple of mine and a few other peoples by putting a better quality gas block on it to stop gas leaks at the block and or by drilling out the gas port in the barrel to give it more gas. Its not really hard to do just get a good set of numbered machine drill bits find out what size its currently drilled out to and try the next size bigger reassemble and test fire... Just put one round in the mag, load that shell and shoot... If it doesnt lock the bolt back on the empty mag tear it apart and drill it out the next size bigger and test fire again... Start small and drill slow, some barrels are extremely hard depending on material and coatings.
