Lancer Systems L5AWM Magazine Features The Lancer Systems L5AWM Magazine is specifically engineered for use with heavy subsonic .300 Blackout ammunition particularly loads using 200 grain and heavier projectiles. Its updated internal magazine geometry allows these longer heavier bullets to stack properly inside the magazine body improving feeding reliability over a standard AR magazine not designed around the Blackout cartridge. A steel and polymer hybrid construction balances strength against unwanted added weight keeping the magazine durable without becoming a burden on the rifle. A stainless steel spring provides consistent long-lasting feeding pressure across repeated loading cycles. This 10-round magazine carries distinctive .300 Blackout markings molded into the body helping shooters quickly identify it among a collection of similarly shaped AR magazines. A contrasting flat dark earth floorplate adds a further visual cue for fast identification in a range bag or on a duty belt. Fitting standard AR-15 pattern rifles this magazine gives Blackout shooters a dedicated option that solves the feeding issues sometimes seen when subsonic ammunition is run through a magazine built for 5.56. For shooters who regularly run suppressed subsonic .300 Blackout loads this magazine removes a common point of failure from the system.
