Aero Precision EPC-9 Slip Fit Magwell (SFM™)

The EPC Slip Fit Magwell (SFM™) brings “extra flare” to your EPC-9, just over doubling the already generous funnel of the receiver. The unique attachment method we co-developed with Darq Industries , termed the Slip Fit, offers users a simplified one piece construction with reduced points of (potential) failure. The hardware follows this simplified approach, consisting of one 4-40 socket head screw and one threaded insert, offering a secure and reliable fit while also keeping the overall weight right at 0.60 oz. For Standard Forged Lowers, please use this model . For Aero M4E1/BA Enhanced, please use this variant . For Radian ADAC, please use this one .
