Lancer L5AWM Rifle Magazine Black .300 BLK 30/rd
$19.99
76 in stock
The L5AWM 300BLK magazine has been specifically engineered for use with heavy subsonic .300 Blackout ammunition particularly with 200+ grain projectiles. The updated internal magazine geometry allows these longer heavier bullets to stack properly which increases feeding reliability when compared to a traditional .223/5.56 magazine. The outside of the mag body is molded with distinctive .300 Blackout markings and the magazine ships with a contrasting flat dark earth floor plate for easy visual identification.
NOTE: These magazines have been specifically designed and optimized to alleviate the stacking and feeding issues commonly experienced when running 200+ grain subsonic .300BLK cartridges in standard .223/5.56 magazines.
If you are shooting lightweight supersonic .300BLK ammunition (<150gr) we recommend using a standard .223/5.56 L5AWM magazine.
