Cpd Magazine Ar15 .400 Legend 5rd Blackened S/s

The .400 Legend is a rising cartridge among AR-15 shooters, and feeding it reliably starts with a magazine purpose-built for the job. This Centerpoint 5-round AR-15 magazine in blackened stainless steel delivers geometry designed specifically for .400 Legend ammunition, eliminating the feeding uncertainties that come with adapting standard magazines to a newer cartridge. If you're running a .400 Legend AR-15 and want dependable function without compromise, a caliber-specific magazine isn't just a luxury—it's the smart choice.

Built from 410 stainless steel and finished with a T-360 coating, this magazine handles rough conditions and storage without the flex or swell problems that plague polymer designs. Whether your rifle lives in a range bag, a truck, or a hunting pack, stainless steel won't degrade from temperature swings or extended loaded storage. The mag is clearly marked with .400 Legend callouts on the body and follower, so there's no confusion when you're grabbing mags in the field or at the bench.

The internal geometry—the ribs and cartridge stack—is engineered for reliable feeding and smooth cycling in .400 Legend-chambered uppers. Pair one with a quality bolt carrier and you've got a foundation for consistent performance. The yellow AGF follower and Everflex spring are proven components that keep rounds feeding without fail.
