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.
