This upper assembly is the perfect blend of performance and style, featuring a precision-crafted 20" bull contour barrel that ensures long-lasting durability and consistent accuracy for all your shooting needs.

Unmatched Accuracy with a Bull Barrel: At the heart of this upper assembly is the 20" 416 stainless steel bull contour barrel.

With a .936 diameter under the gas block, the barrel is strong and stable, providing you with optimal performance. The target crown at the muzzle ensures precision shot placement, making this upper assembly ideal for both range shooting and tactical use.

Durable and Reliable Upper Receiver: The A3 flat-top upper receiver is crafted from 7075-T6 aluminum, offering a tough and reliable platform for your upper assembly. The black hardcoat anodized finish enhances corrosion resistance, ensuring long-lasting durability in harsh environments. Equipped with M4 feedramps, forward assist, and a dust cover, it provides flawless cycling and reliability in any conditions.

Smooth Gas System for Reliable Cycling: With a .936 micro gas block and rifle-length gas system, this upper assembly is designed to provide smooth and efficient cycling for every shot. Whether you’re running your AR-15 for precision shooting or tactical drills, the gas system ensures consistent performance.
