D&H AR-15 .300 BLK 30-Round Aluminum Magazine with Red Follower

Description

Running a .300 Blackout AR and still feeding it out of a 5.56 mag? That works in a pinch, but it's not doing you any favors. D&H Industries built this 30-round aluminum magazine specifically for BLK, with internal ribs and feed lips tuned for the fatter .30 caliber projectiles so rounds stack and strip cleanly instead of nosing into each other. It's the kind of upgrade that quietly makes your rifle run smoother, especially once you start mixing subsonic and supersonic loads.

What Sets the D&H .300 Blackout Magazine Apart

The body is 6061 T6 aircraft-grade aluminum wearing a hard-coat anodized black finish, so it shrugs off range abuse and holds up against corrosion. Inside you'll find a 17-7 PH stainless steel spring that comes pre-compressed and passivated, which is D&H's way of keeping feed pressure consistent over a long service life. The internal rib placement is dimensionally adjusted for .300 BLK, and because these are built off proven 5.56 parent magazines, they'll still run in a 5.56 rifle if you ever need them to.

The Red Follower and Why It Matters

That bright red proprietary limited-tilt follower isn't just for looks. It resists binding and helps keep rounds tracking straight up the mag, and the high-visibility color plus laser-engraved caliber marking make it dead simple to tell your BLK mags apart from your 5.56 stock at a glance. Keeping calibers clearly separated is smart practice when you're running multiple ARs, and this mag makes that easy.

D&H has been building dedicated .300 Blackout aluminum magazines longer than most, and they've earned a reputation at the range, in competition, and out in the field. If you like the feel and durability of a metal-bodied mag over polymer, this is a solid, affordable way to build out your BLK rotation. Grab a few and stash them with your rifle so you're never short on the loaded ones.
