Review on HK Quick-Change CO2 Cartridge Adapter for SIG SAUER MPX 💨 and MCX Air Gun Rifle with 88g or 90g Bottle Threads by Jeff Rhodes

Bought for my sig mpx as I thought it would be good to have it in a 90 gram bottle. Works as it should, has two uses. Adapter into your gun, then insert the bottle into the body and then screw it into your gun and you won't lose any CO2. If you use it it has enough gas to fire maybe 10 shots effectively then you can just throw your bullets far away lol. Also, once empty, the CO2 cylinder will get cold and get stuck in the body if it expands or presses against the back of the adapter and jams. I'm sending it back but it does what it promises. basically lol
