About the Umarex H&K USP Co2 Gas Blowback Magazine:
This is the correct Magazine for the Umarex H&K USP Co2 Gas Blowback (GBB) Airsoft Pistol. This has a 18 round capacity and metal construction. It is the factory OEM magazine that comes with your pistol. It includes a new Hex Wrench for tightening and loosening the threaded co2 cartridge base plate. This magazine only works in the Co2 GBB USP Model Number #: 2275043 this will not work in the KWA/Umarex Green Gas Blowback Pistol. It also does not work in the NBB (Non Blowback) Co2 Powered USP. The magazine is fully licensed by Heckler & Koch. This is such a fun gun to shoot I would recommend carrying additional magazines into the airsoft field.
Q: Will this magazine work with my Green Gas HK USP airsoft gun?
A: No, this one will only work with the HK USP Co2 Blowback Pistol Factory Part Number: 227504
Q: How do I put in the Co2?
A: Insert the provided hex wrench into the magazine and turn it counter clockwise until the cap is removed, Insert a fresh Co2 cartridge into the magazine, insert a fresh co2 cartridge, place the cap back on the bottom of the magazine, take extra care that the threads are aligned and you are not going to end up cross threading the cap, tighten the cap/base plate until it just barely touches the co2 cartridge (finger tight), then in one motion tighten up the plug more until it punctures the co2 cartridge and stops hissing. There is no need to over tighten the bottom. You just need to tighten it until the co2 is no longer leaking out. Please do not go beyond that point by much as it will damage the seal overtime.
Q: How do I maintain my magazine?
A: Put a couple of drops of pure silicone oil (available here) on all rubber seals and o-rings.
