The CMMG 9mm Radial Delayed Blowback Upper is a testament to precision engineering and innovative design. Renowned for their expertise in AR-15 rifles, CMMG extends its mastery with this conversion kit that transforms your firearm experience into something both unique and efficient.
At the heart of this upper is the 5-inch medium taper barrel, crafted from durable 4140 chrome moly steel. This material choice ensures longevity and reliability under various conditions. The barrel's interior and exterior are treated with a salt bath nitride finish, providing superior resistance to corrosion while enhancing performance.
The upper features a 1:10 twist rate, optimized for stabilizing projectiles across different velocities—a key component in achieving accuracy shot after shot. Chambered in the widely respected 9x19 NATO caliber, it offers versatility suitable for both training purposes and personal defense scenarios.
A standout feature of this offering is its patented radial delayed blowback bolt system. Unlike traditional direct blowback systems, this innovation reduces felt recoil without sacrificing reliability or speed—an advantage particularly beneficial during rapid fire sequences.
Attention must be given to compatibility; an enlarged ejection port is necessary to ensure smooth operation when utilizing this upper on your existing lower receiver assembly. Weighing in at just 1.4 pounds, it represents an ideal balance between maneuverability and robustness.
CMMG continues to push boundaries within firearms technology with products like these designed not only for enthusiasts but also those who demand uncompromised quality from their equipment.
