Key Features:
Modified 10” Diamond Series Upper: Crafted with precision, the 10” Diamond Series upper ensures uncompromising performance and durability. An added cut in the top of the Picatinny rail allows for easy access to the adjustable gas block to make gas adjustments.
SilencerCo ASR Muzzle Brake: This 3-port muzzle brake is compatible with all SilencerCo ASR Mounts so you can shoot suppressed for any demand. This compatibility ensures a seamless integration between the upper and SilencerCo’s silencers. It offers quick and easy one-hand-on, one-hand-off attachment and detachment. The 3-port design effectively reduces felt recoil and muzzle climb.
Superlative Arms Adjustable Gas Block: The inclusion of the Superlative Arms adjustable gas block allows shooters to fine-tune their rifle’s gas system. This not only optimizes performance but also contributes to a smoother shooting experience, minimizing recoil and enhancing overall control.
Gas-Defeating Charging Handle: The SilencerCo gas-defeating charging handle creates a seal between the rear of the upper and lower receiver to redirect gas flow away from the shooter’s face, ensuring a cleaner shooting experience while using a silencer.
NOTE: This upper will come with the BCG and the SilencerCo charging handle
