Why a Dedicated 300 BLK Mag?
While some 300 BLK ammo runs consistently in 5.56 magazines for some users, others have found it to be problematic. At the request of some demanding professional users, we have designed an ultra-reliable magazine dedicated to handling the challenges of various 300 BLK ammunition types.
Optimizes Round Stack
300 BLK rounds come in a variety of shapes and sizes, and some don’t interface correctly with the contact areas in a 5.56 mag. This can ultimately cause stoppages. By designing a PMAG® specifically for 300 BLK, we were able to optimize the round stack for the increasing variety of 300 BLK projectiles.
Minimizes Side Pressure and Friction
Dust or suppressor fouling magnify the problem—especially with certain subsonic rounds. This creates side pressure within the mag, adding friction and slowing the stack movement upwards. Commonly misdiagnosed as a spring issue, this is a geometry issue that our PMAG® 30 AR 300 B GEN M3™ is engineered to solve.
Avoids Caliber Misidentification
The dedicated PMAG® for 300 BLK includes tactile and visual cues that differentiate it from 5.56 PMAGs for those who need to switch types of ammunition rapidly, avoid dangerous misidentifications and cross loading.
Maintains PMAG Reliability
Along with the corrected geometry for a perfect round stack, the PMAG® 30 AR 300 B GEN M3™ carries forward all of the other features that the PMAG is known for, like long-life stainless steel springs, four way anti-tilt followers and constant curve internal geometry. This all adds up to bring you the flawless performance that Magpul® is known for with nearly any 300 BLK ammo.
