Spare Firepower For Your USP Compact

A gas blowback pistol is only as good as the number of loaded magazines in your pouch. This ASG USP Compact spare gas magazine lets you carry extra rounds and swap in fresh gas on the fly, so a quick reload keeps you in the game rather than fumbling to top up mid firefight.

Built To Last

The magazine uses a full metal body for durability and a solid gas reservoir, feeding 6mm airsoft BBs through a spring loaded follower. Green gas fills through the base valve and powers a satisfying blowback action in the ASG H&K USP Compact platform.

Care And Handling

Add a drop of silicone oil to the fill and release valves every so often to keep the seals soft and leak free. Store the magazine with a little gas left in it and keep spares warm on cold days for the strongest cycling.

Frequently asked questions

Which pistol does this magazine fit?

It is a spare magazine for the ASG H&K USP Compact gas blowback pistol. Always check your own pistol model and generation before buying, as USP variants can differ.

What gas does it use?

It runs on green gas, filled through the valve in the base of the magazine. Add a drop of silicone oil to the fill valve now and then to keep the seals healthy.

What BB size should I use?

Standard 6mm airsoft BBs. Good quality seamless BBs feed best and help avoid jams or barrel damage.

Why does performance drop in cold weather?

Green gas loses pressure as temperature falls, so power and cycling can weaken on cold days. Keeping spare mags warm in a pocket helps a lot.

Do I need to be 18 to buy this magazine?

This is a magazine accessory rather than a gun, so it does not carry the same restrictions as a RIF. You do still need to be old enough to hold a payment card to order online.
