Improving on our Mod-2 wasn't an easy task but we felt we could push the quality of our 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 more in a duty environment. - FEATURES: - 30-round magazine. - 300 Blackout compatibility. - Sturdy impact-resistant polymer with textured grip. - Anti-tilt follower. - Heavy-duty non-memory and non-corrosive stainless steel spring. - Made in the U.S.A. - Material able to cerakote.
