Upgrade your 12-gauge AR-platform or MKA1919 shotgun with the Sierra Defense 20-Round 12-Gauge Drum Magazine, engineered for serious capacity and dependable performance. Constructed from high-strength, lightweight polymer, this patented design was stress-tested through 10,000 rounds to ensure consistent feeding and rock-solid reliability in demanding conditions. A streamlined internal system reduces the number of moving parts, making maintenance faster and cleaning easier while enhancing long-term durability. The reinforced, corrosion-resistant steel feed tower stands up to harsh environments, and the compact profile maintains balanced handling despite the extended 20-round capacity. A quick-release winding wheel and clear visual round count window simplify loading, so you can spend more time shooting and less time reloading. Whether you\'re running drills, competing in 3-gun, or maximizing range time, this drum magazine delivers extended performance in a rugged, user-friendly package. NOTE: Will not work with most AR-12 mag-fed bullpup shotguns due to the proximity of the mag to the pistol grip.
