CVA CR3905R Cascade SB 450 Bushmaster 18" 5-Round Threaded Barrel Rifle

The CVA Cascade SB 450 Bushmaster 18" 5-Round Threaded Barrel Rifle is purpose-built for operators and precision shooters who demand a compact, magazine-fed platform chambered in the proven .450 Bushmaster cartridge. Designed for those transitioning from AR-pattern systems or seeking a modern lever-action alternative with semi-automatic capability, this rifle delivers stopping power in a form factor that doesn't sacrifice ergonomics or reliability. The 18-inch barrel strikes the critical balance between velocity, maneuverability, and practical accuracy at typical engagement distances—making it equally suited for hunting medium-to-large game or defensive scenarios where a short-action rifle offers tactical advantages.

Built on CVA's proven modular platform, the Cascade SB features a threaded 18-inch barrel that accepts common muzzle devices, allowing customization of sound signature, recoil management, and ballistic performance to match your mission profile. The five-round magazine capacity reflects the .450 Bushmaster's substantial case capacity and recoil characteristics, optimizing reliability and feed consistency in field conditions. At 8.4 pounds, the rifle maintains a manageable carry weight without sacrificing structural rigidity or mechanical durability. The compact 45.7-inch overall length makes it ideal for vehicle-mounted operations, confined-space entries, or sustained off-hand shooting—a critical advantage when split-second target acquisition matters. CVA's quality control ensures consistent headspacing and chamber dimensions, translating to sub-minute accuracy potential when paired with appropriate optics and ammunition.

This rifle suits hunters, tactical professionals, and sportsmen who leverage the .450 Bushmaster's inherent advantages—deep penetration, minimal over-penetration liability in mixed environments, and proven performance on large game at intermediate ranges. The threaded barrel opens compatibility with suppressors (subject to local NFA compliance), flash hiders, and muzzle brakes, enabling operators to tailor ballistic profile and signature to threat environment. Installation of optics, lights, or other accessories leverages standard Picatinny rail mounts where factory provisions exist. Law enforcement and military end-users appreciate the rifle's robust mechanical design and .450 Bushmaster's reputation for reliable expansion in duty-grade ammunition, while civilian shooters value the round's inherent stopping authority and controllable recoil impulse.
