Whether you're looking for a hunting rifle, competition build, or a reliable upper for tactical applications, this 6.5 Grendel upper offers superior performance with every shot.

Key Features:

  • 20" Spiral Fluted 416 Stainless Steel Barrel: This barrel is chambered in 6.5 Grendel Type 2, offering enhanced accuracy and long-range capability. The spiral fluted barrel provides weight reduction, improves heat dissipation, and enhances the barrel’s cooling properties for consistent accuracy during extended shooting sessions. Hardened to 26-32 RC and stress-relieved, this barrel is perfect for sustained use.

  • Triport Muzzle Brake: The Triport Muzzle Brake helps minimize recoil and muzzle rise, giving you better control and quicker follow-up shots. It's designed to reduce muzzle flash and improve accuracy in any shooting environment, making it ideal for precision shooting, competition, and tactical use.

  • Rifle-Length Gas System: The .750 low-profile gas block and rifle-length gas tube ensure smooth cycling and consistent gas flow for reliable operation. Whether you’re shooting long distances or engaging in rapid-fire scenarios, the rifle-length gas system delivers reliable performance.

  • A3 Flat Top Upper Receiver: Made from 7075-T6 aluminum, the A3 flat top upper is anodized to military specifications for durability and corrosion resistance. It includes M4 feed ramps, a forward assist, and a dust cover, providing seamless operation and functionality.

  • 15" M-LOK Free Float Handguard: This lightweight, ergonomic M-LOK handguard offers a sleek design that is perfect for adding accessories while maintaining a slim profile. The 15" free-float design reduces the chance of accuracy-reducing pressure and allows for precise customization of your build.
