Smith & Wesson M&P15-22 Long Magazine .22 LR Black Polymer 10/rd

The Smith & Wesson M&P15-22 Long Magazine in .22 LR is a rimfire-specific magazine engineered for the M&P15-22 rifle platform. Built from one-piece molded polymer, this 10-round magazine delivers reliable feeding and handling of .22 Long Rifle ammunition. The textured gripping surface ensures secure purchase during magazine changes under field conditions, making it a practical standard-capacity option for training, sport shooting, and marksmanship development where .22 rimfire ammunition provides cost-effective volume practice.

The polymer construction weighs just 0.7 pounds empty, keeping magazine loadout minimal during extended range sessions. The absence of a load assist button means manual seating of rounds during loading—a design choice common in rimfire magazines that reduces complexity and potential failure points. The compact footprint (4.85 x 1.4 x 10.95 inches) fits the M&P15-22 receiver profile without protruding, maintaining the rifle's overall geometry for storage, transport, and use from improvised positions. Manufactured in the USA, this magazine meets the original equipment specifications for the M&P15-22 platform.

This magazine is purpose-built for shooters operating the Smith & Wesson M&P15-22 rifle in civilian training, youth marksmanship programs, or suppressed-fire scenarios where .22 LR offers subsonic ballistics and minimal noise signature. The 10-round capacity aligns with many state-level legal requirements for rimfire sporting rifles while providing sufficient round count for practical zero verification, sight-in procedures, and continuous-fire training strings. Acquiring spare magazines ensures uninterrupted training without range downtime spent reloading between strings.
