This AR15 upper receiver assembly comes ready to attach to any Mil-Spec lower receiver. It is built around a 16 inch, stainless steel straight fluted barrel that is chambered in .223 WYLDE. This versatile chambering provides the capability of shooting .223 Rem or 5.56 NATO cartridges. The upper receiver is a forged M4 flat top upper, allowing you to easily attach rifle scopes and red dot sights to the picatinny rail.
The Silver Streak upper features stainless steel, aluminum, and silver anodized parts that provide an aesthetic contrast and appearance. Silver Streak components include a stainless-steel muzzle brake, matt aluminum ejection port cover, silver anodized forward assist, stainless-steel forward and rear takedown pins, and a stainless and silver anodized anti walk/rotation pin set.
This upper assembly features a .223 Wylde stainless-steel straight flute barrel and is outfitted with a 13.5″ CBC M-LOK handguard featuring durable attachment points for accessories and generously sized M-LOK cuts allowing maximum air circulation around the barrel for faster cooling while also keeping the handguard cool to the touch. This handguard also features picatinny top rail sections that sits flush with the upper receiver.

➲ Straight Fluted Barrel
The barrel is one of the few components that directly affect the accuracy and weight of your build. Designed for corrosion resistance, this barrel will not let you down. Due to being machined from 416-R Stainless Steel, this barrel contains a better cut, higher-definition rifling, crowns, and chambers, resulting in the ability to stay more accurate over its usable life. This barrel utilizes the popular and versatile .223 Wylde chamber, which allows for the safe usage of 5.56 NATO ammunition and enhance reliability. This is the perfect barrel for an AR build, keeping weight to an absolute minimum due to the fluting, while still offering a significant ballistic advantage.
The muzzle device is designed to perform a specific task, like suppress flash intensity or reduce felt recoil. This compensator is machined from quality steel for a lifetime of service.
