Bushmaster M4 Patrolman's 5.56 NATO 16" Barrel 10+1 Capacity

The Bushmaster M4 Patrolman's delivers reliable semi-automatic performance in the proven 5.56x45mm NATO caliber. This carbine combines military-spec components with civilian accessibility, featuring a 16-inch chrome-lined barrel that meets federal requirements while maintaining effective ballistics for multiple applications.

What Makes This Different

Built on a forged aluminum receiver with mil-spec dimensions, this rifle accepts standard AR-15 magazines and accessories. The chrome-lined barrel extends service life significantly compared to standard steel barrels, while the carbine-length gas system provides reliable cycling with various ammunition weights. The 6-position collapsible stock adjusts from 10.75 to 14.25 inches length of pull, accommodating different shooter sizes and tactical gear configurations.

Key Features

• 16-inch chrome-lined barrel with 1:9 twist rate for stabilizing 55-77 grain bullets
• Forged 7075-T6 aluminum upper and lower receivers with Type III hard coat anodizing
• 6-position collapsible stock with mil-spec buffer tube threading
• A2-style flash hider reduces muzzle flash and provides modest recoil mitigation
• Standard AR-15 magazine well accepts STANAG 4179 compatible magazines
• Picatinny rail system allows mounting of optics and accessories

Field testing demonstrates consistent accuracy potential of 2-3 MOA with quality ammunition, suitable for law enforcement patrol duties, competitive shooting, and sporting applications. The carbine-length gas system functions reliably with ammunition ranging from 55 to 77 grains, while the chrome lining resists corrosion in adverse weather conditions. The platform's modularity allows users to customize trigger groups, stocks, and barrel configurations as needs evolve.
