Ar10 cycling issues?
I recently bought this m&p 10 and before I shot it I decided to upgrade the handguard and obviously the gas block as well. The gas block is a low profile titanium unit from vseven and the handguard is an apex technologies. The issues are as follows. The first 3-5 rounds the gun will cycle and pick up a round no problem, but once a few rounds are spent it just will not pick up another round. The bolt is overcoming the magazine and skipping right over the next round. Overgassed? Underweight? I’m stumped.
