Review on 🔌 CO2 Bulk-Fill Adapter for Umarex EBOS by Air Venturi by Ernest Duckett

Works but has a design flaw. The pressure release hole is too big, sharp, and the bezel is too thin. It's also not a right angle. All of this contributes to excessive wear on the nylon seal in my rifle. This adapter cuts the ring in nylon. So nothing came out of the gun. I hope it stays that way. I recommend anyone buying this for use with sig mcx/mpx to hand tighten and ignore the Aur venturi tuning video that says you need to tighten them with an Allen wrench to tighten. The right hand is enough.
