DuraMag SS 400 Legend 5-Round AR-15 Magazine, Stainless Steel Black

The DuraMag SS 400 Legend is a 5-round magazine for AR-15 pattern rifles chambered in 400 Legend. It is built from 410 stainless steel and finished in black with a T-360 coating.

The magazine is marked with "400" on the body and follower for quick identification of the caliber. The listing describes .400-specific rib geometry intended to support feeding and round stacking, and states that the magazine is safe for extended storage while loaded. The raw retailer text also describes a 10-round version, which is not reflected in the structured capacity of this listing.
