The slender appearance of the E2ARMD4 muzzle device from Mission First Tactical belies the huge dividends it provides in recoil mitigation. Weighing in at 2.75 ozs., and measuring 2.25"-long, the tapered, nitride-treated, 416 stainless steel compensator features two angled ports at its top to counteract muzzle rise, while a total of six side ports mitigate rearward movement. Designed to fit rifles bored for 0.244" bullets and smaller, the unit comes threaded 1/2x28 TPI. A crush washer is also included. MSRP: $100. missionfirsttactical.com.
