Sig Sauer MCX/MPX Air Rifle 30-Round Pellet Magazine

The Sig Sauer MCX/MPX air rifle 30-round pellet magazine brings semi-auto speed to your pellet gun. If you're running a Sig MCX or MPX ASP and want to spend less time reloading and more time sending rounds downrange, this magazine's rotary pellet drive system lets you fire up to 30 rounds in just 3.5 seconds—a meaningful step up from single-shot or traditional tube-fed pace.

What sets this magazine apart is its engineering: rather than fumbling with individual pellets or slow mechanical feeds, the rotary system smoothly indexes 30 pellets per belt, and Sig includes three refillable belts with each magazine. That means you get 90 rounds of ready-to-go capacity before you need to refill a belt. Build quality is solid too—the magazine is constructed from rugged polymer composite, designed to survive the kind of use Sig puts its firearms and air rifles through.

Available in both .177 and .22 caliber, so make sure you match your rifle's bore. The compact footprint (5" L × 2" W × 1" D) won't add bulk to your gun. Whether you're running target drills, varmint shooting, or just want the satisfaction of letting loose rapid-fire strings, this magazine transforms how your MCX or MPX ASP handles.
