Whether it’s knocking down a long-range shot or tracking a moving target, speed and accuracy remain a shooter's main goals. To meet these challenges, CMMG has introduced the Mk4 V and Mk4 V2, both chambered in 5.56x45mm.

Both the Mk4 V and Mk4 V2 are equipped with a 24-inch fluted 416 stainless steel barrel designed to extract the utmost performance out of each round. The fluting on the barrel reduces the weight and also allows the barrel to dissipate heat more rapidly, thus cooling down faster.

The rifle also features CMMG’s RKM14 KeyMod hand guard, which offers three primary advantages:

• Reduced Weight
Material is removed from the hand guard where the KeyMod slots are located making it lighter than traditional quad-rail hand guards.

• Slimmer Profile
The absence of rails from the sides of the hand guard create a thinner profile that is easier for the average shooter to wrap their hand around and grip.

• Easy Accessory Attachment
The KeyMod slots are found at the 3, 6 and 9 o’clock positions on the hand guard. Accessories that are KeyMod compatible can be attached directly to the slots, whereas accessories that are not KeyMod compatible can easily be attached by using one of CMMG’s 5-slot accessory rails.

A standard 1913 Picatinny rail runs atop the rifle from the charging handle to the front of the RKM14 hand guard for mounting optics.

The Mk4 V2 comes standard with a Geissele Automatics SSA two-stage trigger pre-installed. The Mk4 V2 comes with standard with a Magpul MOE pistol grip and buttstock and one 30-round Magpul PMAG. The Mk4 V2 is available now and the MSRP is $1,499.95.

The Mk4 V, is a less-expensive option and comes with CMMG’s renowned single-stage mil-spec trigger, an A2 pistol grip and an A1 butt stock. MSRP for the Mk4 V is $1,249.95.
