Precision Reflex Nosler Magazine AR15/M16 6.8mm/.224 Valkyrie/.22 10 Round Black. 8mm SPC waffle magazines with push button floor plate are constructed of butt welded steel halves to create the best internal volume for the magazine. We use Magpul anti-tilt follower with spring and push button floor plate allows for magazine to be quickly disassembled for cleaning. The magazine is 3.7in in length. This is newer design we have removed the Waffling from the outer edges of the magazine to quiet down the magazine and reduce follower drag. Magazine also works for the .224 Valkyrie and the .22 Nosler.
