CMMG MK4 RCE 5.56mm

The series of letters in the brand and model may be daunting, but behind them is an AR rifle of real merit. The MK4 RCE’s forged M4 upper and AR-15 lower are of carefully machined 7075-16 alloy. Inside there’s a Geissele Automatics SSA two-stage trigger. The Magpul CTR adjustable stock complements an RKM 14 KeyMod free-floating handguard. CMMG gave the stainless, 16-inch, 5.56mm NATO barrel a fast 1-in-7-inch rifling twist and its own nitride-finished muzzle brake. A Picatinny rail runs the length of this rifle. The MK4 RCE is also available in 300 AAC Blackout. Unloaded, the rifle weighs 6.5 pounds. Add a pound if you load the 30-round Magpul magazine. For more information, visit cmmginc.com.
