Thread: AR15 - Question for you

So break it down into two questions:

Dented cases: Pop a bit of foam tape over the case deflector, then try again to see if it's still denting the cases. If you're using an adjustable gas block, you can basically dial it open until it's locking the bolt back ( one round loaded each time ), then one click or half turn further open.

Dirty cases: Yes they shit where they eat hahahaha
