Which aftermarket parts enhance .450 Bushmaster accuracy?

Upgrading the Barrel

A heavy match-grade barrel is essential for achieving optimal accuracy in a .450 Bushmaster rifle. Look for barrels made from high-quality, stress-relieved stainless steel or chrome-moly steel, and weigh at least 22 inches with a 1:10 or 1:12 twist rate. This will provide the stability and consistency needed for accurate long-range shots. For example, a 28-inch, 1:10 twist, 1.5-inch OD barrel from a reputable manufacturer like Bartlein or Krieger can offer exceptional accuracy and durability.

Controlling Recoil and Vibration

A muzzle brake or compensator can significantly reduce recoil and vibration, allowing for faster follow-up shots and improved accuracy. Opt for a brake or compensator specifically designed for heavy recoiling cartridges like the .450 Bushmaster, and look for products with a high gas volume or a proprietary “baffle” design to effectively manage recoil. For instance, the Gemtech Outback or the SilencerCo Omega 300 can provide effective recoil reduction while maintaining accuracy.

Optics and Stocks

A high-quality optic scope with a good reticle is crucial for accurate aiming in a .450 Bushmaster rifle. Consider scopes with a first focal plane reticle, such as the Leupold VX-3 or the Nightforce ATACR, which provide a clear and accurate aiming point at various magnifications. Additionally, a well-crafted stock, such as a McMillan or H-S Precision, can provide a solid foundation for accuracy and help stabilize the rifle during firing. Look for stocks with a comfortable LOP (length of pull) and a well-designed cheekpiece to promote proper shooting form and accuracy.
