I am new to ARs and having an issue with an AR10 308 I put together.
Purchased a 308 upper build kit from Delta Team Tactical. 20" barrel, aero upper. I do not recall the barrel or bcg manufacture.
I put this together took it out and shot about 5 rounds very slowly and it cycled as expect then stopped cycling. Cleaned it checked the gas port was properly aligned and clean. Took it back out no change.
Thought maybe it was under gased. Ordered a JP adjusted gas block and new tube.
Followed JP's instructions on setting it up and still will not cycle. Even when fully open. Shot 40 rounds adjusting the block 1/2 turn at a time.
My gas port on my barrel is approximately 0.080 7.125 from the muzzle barrel at block is 0.75.
Could my port be to small or is there another thing I need to try? Any thoughts or ideas are greatly appreciated.
