Key Features:

• Barrel Construction: The 10.5" barrel is made from 4150CMV steel, featuring a black nitride finish for superior durability and corrosion resistance. The barrel is chambered in .450 Bushmaster with a 1:24 RH twist rate for optimal accuracy. The .750" under gas block diameter and 5/8x32 threading offer excellent compatibility with muzzle devices.

• Magnum Linear Comp: The assembly includes the Kaw Valley Precision Magnum Linear Comp, a 3.25" muzzle device constructed from hardened steel with a sleek black finish. The linear comp helps redirect muzzle gases forward, reducing felt recoil and making for a smoother shooting experience. It’s an essential component to help tame the powerful recoil of the .450 Bushmaster cartridge.

• Gas System: This upper includes a .750 low-profile gas block, crafted from high-quality aircraft steel. Paired with a carbine-length stainless steel gas tube, it ensures reliable cycling and smooth operation for your AR-15.

• Handguard: The 10" slim-profile M-LOK free-floating rail gives you maximum customization options for mounting accessories. Made from aircraft-quality aluminum and finished with black hard coat anodizing, it offers both lightweight design and durability. You can choose between M-LOK or quadrail options to suit your preferences.

• Test Fired for Functionality: The upper comes fully assembled and test-fired for cycling reliability, ensuring you're ready for the range immediately upon installation.

• Important Notes: This assembly does not include a BCG (bolt carrier group) or charging handle, which can be purchased separately to complete your build. Images may not reflect the exact configuration of the product, so please refer to the product details for accuracy.
