Driven Arms AR Standard Forged Slip Fit Magwell (SFM) - FDE

Driven Arms

Overview

Driven Arms Slip Fit Magwells (SFM) are one-piece nylon polymer magwell flares, co-developed with Darq Industries, that slip over the front of the lower receiver's magazine well and lock in with a single 4-40 screw and threaded insert. They are low profile and snag-free, leave the manual of arms unchanged, and weigh about 0.55 oz with hardware. This model fits most mil-spec forged AR-15 lowers, including Daniel Defense, Geissele, BCM, PSA, Anderson, Spikes, standard Aero lowers and the HK MR556 A4, and enlarges the magwell opening by more than 150 percent. Made in the USA with a lifetime warranty. This listing is the FDE version.
