Winchester 4+1 .308 Win 20" 5-Round Threaded Barrel Rifle

The Winchester 4+1 .308 Win 20" 5-Round Threaded Barrel Rifle by Proof Research delivers precision rifle performance built for tactical professionals, hunters, and precision shooters who demand reliability in demanding environments. This platform combines proven Winchester engineering with Proof Research's reputation for match-grade accuracy and durability. The 4+1 magazine configuration—four rounds in the magazine plus one chambered—provides practical capacity for field operations, competition shooting, and high-round-count training scenarios where reload discipline and controlled fire matter.

The 20-inch barrel with threaded muzzle is purpose-built for suppressor integration, allowing shooters to reduce signature and recoil impulse during tactical operations or training without sacrificing the inherent ballistic advantages of the .308 Winchester cartridge. The threaded design accepts standard 5/8x24 suppressors and muzzle devices, enabling customization for specific mission profiles. Weighing 12.76 pounds, the rifle maintains a compact profile suitable for vehicle operations, close-quarters movement, and extended patrol scenarios while retaining the inherent accuracy and power of the .308 platform—a proven round for extended-range engagements out to 800+ yards in professional and civilian hands alike.

Law enforcement tactical units, military marksmen, and civilian precision shooters will find this rifle ideally suited for designated marksman roles, precision hunting, and long-range training. The threaded barrel accepts industry-standard suppressors and brakes without additional modifications, making it compatible with existing operator equipment ecosystems. Proof Research's attention to manufacturing tolerances ensures consistency across multiple rounds, critical for unit cohesion and predictable performance in duty or competition environments. This is a serious tool for serious professionals.
