This easily installed accessory offers 48% faster reloads as the “funnel” lip that extends below the AR receiver mag well helps guide the magazine into place. The finger grooved frontal area aids in firearm handling with out adding significant weight as the 2 piece assembly only weighs 1.5 oz. Molded of black, reinforced polymer, the assembly attaches tightly by means of 3 allen head screws (wrench included) without any permanent modifications or alterations to the lower. Shown separately, and mounted in photo. Made in USA by Armaspec.
