Bought it to give myself another mag for the CO2 USP that is on this site, and in some retail stores. It's great quality- full metal, the weight of it feels great and the gun feels even better to hold with it. Great upgrade from the plastic mag that comes with the gun. CO2 goes in from the bottom, and is locked inside with an Allen Key. WORD OF ADVICE: Grab some silicone lube/oil, and make sure you get a bit on the tip of your CO2 cartridges every other use. The seals are fragile.
Adds weight to the gun
Will last if taken care of.
Seals can go bad quickly if not taken care of.

this is a really good mag. I got two for my non-blowback umarex h&k usp and they work great! I have had no problem with them so far.
they are full metel and really stong. they can take a lot of hits.
the only con might be that they might get petty heavy over time for not as stong airsoft players.
