18" Sepal Barrel for .450 Bushmaster
The 18-inch Sepal barrel is precision-crafted from 4150 Chrome Moly Vanadium steel for exceptional strength and consistent accuracy shot after shot. The 1:10 twist rate is optimized for stabilizing the heavy projectiles typical of .450 Bushmaster ammunition, ensuring reliable performance with bullet weights ranging from 250 to 300 grains. The 18-inch length provides an ideal balance between velocity retention and maneuverability in the field, delivering the terminal performance needed for ethical harvests on deer, hogs, and other medium to large game while remaining manageable in dense cover or from elevated stands.
KAK .458 Compensator for Recoil Management
The KAK .458 compensator is specifically designed for big-bore calibers like .450 Bushmaster, redirecting muzzle blast and gases to minimize felt recoil and muzzle rise. This effective recoil reduction improves shooter comfort during extended range sessions and, more importantly, enables faster follow-up shots in hunting scenarios where quick second shots may be necessary. The compensator's design maintains the balance between recoil control and blast direction, keeping concussion manageable for the shooter while maximizing performance benefits.
Gauntlet Arms Freefloat M-Lok Handguard
The Gauntlet Arms freefloat M-Lok handguard provides a lightweight yet sturdy platform for mounting hunting accessories like bipods, lights, or sling attachments exactly where you need them. M-Lok slots offer direct mounting points without bulky rail sections, keeping your hunting rifle streamlined and weight-forward balance optimized. The freefloat design isolates the barrel from external pressure, maximizing accuracy potential by eliminating point-of-impact shifts caused by sling tension or support hand pressure during field positions. This combination of strength and weight savings makes the handguard ideal for all-day carries in hunting environments.
Purpose-Built Bolt Carrier Group
This upper includes a .458 SOCOM/.450 Bushmaster bolt carrier group specifically engineered for big-bore AR-15 platforms. Crafted from 9310 alloy steel with a nitride finish, this BCG delivers exceptional hardness, corrosion resistance, and longevity even under the increased pressures and stresses of .450 Bushmaster cartridges. The mid-length gas system with micro low-profile gas block ensures reliable cycling across various ammunition loads while maintaining a clean, snag-free profile under the handguard. The 7075-T6 aluminum upper receiver provides the strength needed for big-bore cartridges while the anodized black finish protects against field wear and corrosion.
