From the manufacturer

Improving on the Mod-2 wasn't an easy task, but Amend2 felt they could push the quality of their magazines even further. With new aesthetics, resin, and feature set, the Mod-3 is sure to impress. The Mod-3 is the perfect magazine to load into your duty rifle, store in your kit, or anything in between. Key differences include: Fiberglass reinforced nylon provides all the durability and impact resistance of our Mod-2 mags, but with increased stiffness and temperature resistance. Enhanced aesthetics and texturing provide excellent grip without compromising smooth reloads. While still maintaining the 2 on the baseplate, the Mod-3 sports muted branding to blend in Mfg: Amend2
