NOTE: These magazines are optimized for subsonic 300BLK ammunition which have a wider and more forward-oriented ogive on the projectile. If you are shooting lightweight supersonic 300BLK ammunition (<150gr), we recommend using a standard .223/5.56 magazine, as the geometry of most supersonic cartridges more closely mimics that of a .223/5.56 cartridge.From concept through production, Lancer Systems engineer solutions that make a difference.

Top Shelf Mags

by -

The feed very well. I have confidence that if I leave it fully loaded for extended periods it will not flex or expand due to the steel feed lips. These are top shelf magazines. This becomes obvious the first time you inspect one. The fit and finish is well above average. The magazine body seems like lexan to me, but whatever it is, it's a stout material. I have never had any feeding issues running 300 BO thru these and it also feeds 556 perfectly as well if you needed it for that application in a pinch. If you find these in stock buy them immediately. These are the best 300 BO magazines on the market.

Top notch

Excellent quality

Big fan of the steel feed lips, made of a thicker plastic than other companies. All around great quality and being translucent is very handy as well

All the reviews of these are on par. If you’re hesitating then maybe something else to take into consideration….theyre easy to tell between the stack of Magpul 5.56 mags you have shoved in your closet. So there’s absolutely no mistaking these are your 300blk mags. Food for thought.
