Description
Running a .458 SOCOM means your rifle is only as dependable as the magazine feeding it, and that's exactly where the D&H Tactical 4-round mag earns its keep. Rather than a 5.56 mag with a caliber marking slapped on, this one is purpose-built around the big-bore cartridge, using a D&H proprietary follower designed to feed those wide, heavy rounds smoothly into the chamber. It holds four rounds and drops into any standard AR-15, M16, or M4 lower, so if you've got a .458 upper on a mil-spec receiver, you're good to go.
What Sets the D&H .458 SOCOM Magazine Apart
The body is machined from heat-treated aircraft-grade aluminum and finished in hard-coat anodized black Teflon, which shrugs off scuffs, moisture, and the general abuse of field and range use. Inside you'll find a 17-7 PH stainless spring chosen specifically for corrosion resistance, so it holds up whether it lives in a truck, a hunting pack, or a range bag. The caliber is laser engraved right on the body, which is a small thing that pays off big when you've got mixed mags in your kit and don't want to confuse it with a 5.56.
Why the 4-Round Capacity Makes Sense
Four rounds might sound low if you're used to thirty-round 5.56 mags, but for a hunting-focused cartridge like the .458 SOCOM it's a smart setup. The shorter body keeps the rifle compact and easier to work in a blind, from a vehicle, or off a bipod in the prone. For dropping hogs, deer, or bear at close range, four big-bore rounds on tap is plenty, and the dedicated design means you're not fighting feed issues that plague folks trying to run these cartridges through unmodified polymer mags.
D&H Industries has been building precision magazines out of Wisconsin for decades, and their metal-bodied AR mags have a solid reputation among big-bore owners who've tried the alternatives and come back to these. If you want your .458 to run right, starting with a mag built for it is the way to do it.

Frequently Asked Questions
Will this D&H .458 SOCOM magazine fit a standard AR-15 lower?
Yes. It's designed to drop into any standard AR-15, M16, or M4 lower receiver just like a normal mil-spec mag. As long as you've got a .458 SOCOM upper on your rifle, this magazine will seat and feed as intended.
Why does it only hold four rounds?
The .458 SOCOM is a large-diameter cartridge, so it takes up a lot more room than a 5.56 round. The four-round capacity keeps the magazine short and easy to maneuver, which is ideal for hunting from blinds, vehicles, or shooting from a rest. For most big-game work, four rounds on tap is more than enough.
What makes this different from a regular AR-15 magazine with a .458 label?
This mag uses a D&H proprietary follower built specifically for big-bore cartridges, rather than a standard 5.56 follower. That dedicated design is a big reason big-bore owners tend to see more consistent feeding out of it compared to running .458 rounds through an unmodified 5.56 magazine.
Is the D&H .458 SOCOM magazine durable enough for hard field use?
It's machined from heat-treated aircraft-grade aluminum with a hard-coat anodized black Teflon finish that resists scratches and corrosion. The 17-7 PH stainless spring is chosen for corrosion resistance too, so it holds up well to moisture and the elements whether it's in a pack, a truck, or a range bag.
