这18寸管子是rifle gas，会不会导气过量？

Rifle gas on 18" what you need to concern is undergas not overgas.

啥叫用loctite装的gas block? gas block的固定螺丝沾点blue loctite再拧很正常吧。用了red loctite的才需 ...

blue loctite doesn't work on gas block. it melts after first couple rounds. Use red loctite on gasblocks. and that's how BCM does to their ARs.
