⚙️ Product Details

Its broad forged-lower compatibility makes this the general-purpose SFM for common AR-15 receivers while preserving a snag-resistant profile. Driven Arms Co.'s Slip Fit Magwell expands the usable entry to more than 150% of the factory funnel, helping the magazine find the opening with less visual attention and less demand for perfect alignment.

The single-piece nylon-polymer funnel, one socket-head screw and one threaded insert create a secure, uncomplicated assembly that weighs approximately 0.55 oz. Its low-profile exterior stays free of prominent snag points and leaves the normal manual of arms unobstructed.
