An incredible airgun deserves an equally incredible magazine. The SIG Sauer 30-Pellet Magazine is engineered to elevate the performance of SIG MPX and MCX “advanced sport pellet” (ASP) CO2 rifles to legendary SIG standards. Its cutting-edge design and rugged polymer composite construction makes this top-of-the-line magazine extraordinarily reliable and tears down any and all limitations to firing speed. Using a rotary pellet drive system, the patented SIG “RPM” smoothly feeds 30 rounds per belt – with three refillable belts included – for consistent, optimized firing. You’ve never had as much fun shooting your MPX or MCX ASP air rifle as you will with this rapid-fire bad boy attached. Don’t forget to load up on .177 caliber pellets! All that extra capacity and speed means more pellets used; thankfully, we’ve got pellets and all your other airgun needs covered at the lowest prices you’ll find anywhere!
