"The 22 Nosler caught our eye for a number of reasons," said Chris Reinkenmeyer, CEO of CMMG Inc. "First, it's designed around the AR-15 and so it's very compatible with our rifles and also easy to match up with an existing lower. Second, our customers want rifles that are unique but with purpose." He continued, "Based on our testing, we feel that the 22 Nosler does present significant ballistic advantages for shooters who require a fast, accurate and flat shooting projectile out of a relatively lightweight rifle."
Already SAAMI approved, a 55-gr. 22 Nosler Ballistic Tip round can reasonably expect muzzle velocities approaching 3,500 f.p.s. out of a 24" barrel. Featuring 25 percent more case capacity than the .223 Rem./ 5.56 NATO, the width of the 22 Nosler means that it feeds out of 6.8 Rem. SPC magazines. Despite the larger casing, the rim has been necked down so that the round runs off a standard .223 bolt carrier group.
When paired with this type of ballistic performance, CMMG's Mk4 rifles in 22 Nosler are capable of filling the needs of long-range shooters and a variety of hunting applications.
CMMG's 22 Nosler line-up will include four different rifles, four upper receiver groups that can be paired with any mil-spec AR-15 lower receiver and three barrel sub-assemblies. Each rifle comes standard with a 10-round magazine.
