My target AR constantly short cycles.
1. Numerous times when shooting I will have an empty chamber and will have to cycle it manually. It appears the bolt is not cycling back far enough to pick up the next round in the mag.
2. Every time the last round is fired the bolt will hold open on the follower and not on the BHO. I have to manually pull the bolt back another 1/2" before the bolt will catch on the BHO.
3. It will ALWAYS eject the spent case and never stovepipes.
4. If I have to extract an unspent round for some reason, it take a TON of effort to pull the bolt from battery as if the chamber is too tight.
SPECS-
Pre built DPMS upper with a 16" SS bull barrel.
I have put two gas blocks on it, cleaned the gas tube and gas port.
CMMG lower with DPMS LPK
Carbine buffer and spring.
I have swapped this upper on my other AR with no change in performance. I am starting to think either the headspace is too tight or there is something wrong with the gas system.
Please help.
