Multi-Caliber AR Mag

One of the weakest links in the reliability of the Stoner system is the magazine. Modern synthetic mags have greatly improved the situation, but things still get weird when you try and make an AR feed rounds other than 5.56mm. This year at SHOT Show I saw what one company thinks might be a solution for feeding different cartridges in the form of a multi-caliber magazine. The UNIMAG is RZE’s first production-ready firearm component and it claims to provide greater flexibility in ammo choice for gun owners and enthusiasts.

It’s compatible with AR-15s and other rifles that use a STANAG magazine, and is reportedly proven reliable and functional with at least six different types of ammunition. The secret is a two-piece, self-leveling follower that maintains stability while accommodating the changing shape and taper of different cartridges, and a self-adjusting magazine shell that adjusts to various cartridge diameters. Compatible cartridges include .223-Rem. and all of the cartridges based on that case (5.56mm, .300 BLK, .204 Ruger), 5.45×39, 6.8 SPC, 7.62×39, 6.5 Grendel and .458 SOCOM.
