The Magpul M3 PMAG for .300 Blackout is specially designed to handle all of the different bullet weights the .300 Blackout round can use. The M3 PMAG for .300 Blackout has a distinct rib design and smoother upper-half texture that are both visually and tactile different than other caliber PMAGs to mitigate dangerous cross-loading issues. The M3 PMAG features Magpul's next-generation impact and crush resistant polymer, aggressive texturing, an easily removable slim floor plate, a paint pen dot matrix for marking and identification, and a dust/impact cover.
