The MagPul 20LR PMag is constructed from advanced polymers with superior impact resistance and light weight. This 20-Round magazine is designed to replace the standard SR25/ M110 pattern magazines. The 20LR is less than half the weight of a standard steel mag and has a true 20-round capacity. The body is designed with a constant-curve inside dimension and a self-lubricating follower for reliable feeding. The textured magazine body and flared floorplate improve handling over standard magazines. The snap-on impact cover protects the feed lips from impacts and debris while in storage. The impact cover also allows loaded magazines to be stored long-term (over 1 year) without compromising the integrity of the feed lips. The design of the floor plate is simple to disassemble using the impact cover or simple punch for cleaning and maintenance.


The 20LR PMag will fit KAC SR25, DPMS LR-308, LWRCI REPR, Larue Tactical OBR, Bushmaster 308 ORC, Lewis Machine & Tool MWS, Remington R-25, POF P-308, JP Enterprises LRP-07, G.A. Precision GAP-10, Armalite AR10A, Les Baer 308 Semi-Auto Rifles and other rifles that use the SR25/ M110 pattern magazines. 20LR Pmag is not compatible with Armalite AR-10 (except for the AR-10A), RRA LAR-8, or M1A/M14 variant rifles.
