“This is the first magazine that can handle the 223, 6.5, 6.8 and the 2 AK calibers, the 7.62x39 and 5.45x39, reliably. It offers OEMs a tremendous opportunity to expand their AR-15 product families, particularly in 7.62x39 uppers and lowers,” CEO & Founder Ed Ross said.

The UNIMAG multi-caliber magazine, Ross Defense Systems’ first production-ready firearm component, provides enhanced performance and reliability for gun owners and enthusiasts. Compatible with AR-15 and other rifles that use a STANAG magazine, the UNIMAG is proven to be reliable and functional for eight different types of ammunition and counting. The patented design includes a two-piece, self-levering follower that maintains its stability while also accommodating tilt introduced by the ammo, and a self-adjusting magazine shell to regulate various cartridge diameters.

Ross Defense Systems' proprietary technology is backed by patents, including the self-levering follower for a universal magazine of multiple caliber compatibility for firearms (US 8667724 B2) and the magazine shell of a universal magazine of multiple caliber compatibility for firearms (US 8850732 B2).
