the PMAG 20 LR/SR GEN M3 is a lightweight, cost effective, highly reliable magazine for SR25/M110 pattern rifles. It features true 20-round capacity, a constant-curve body and an anti-tilt follower. Low profile ribs and an aggressive front and rear texture give positive control of the GEN M3 in all environments, and a paint pen dot matrix at the bottom panel of the body to allow easy marking by the end user for identification.
