Not to derail but I need to throw a duster gas question out there.
I occasionally use Duster on my MP7, shoots a bit hard for CQB. I use Falcon Dust-Off that I can get in bulk from Costco (only reason I will ever have a membership). Problem is, the plastic nozzle breaks off easily. I've wasted 2 cans of duster, nearly full because the plastic lip or nozzle breaks off with the AI adapter attached. Anyway around this?
