Bushmaster M4 Patrolman's 5.56 NATO 16" Rifle 30+1 Black

The Bushmaster M4 Patrolman's Carbine delivers proven AR-15 platform reliability in a patrol-ready configuration. This 5.56x45mm NATO rifle combines military-specification components with civilian-legal features for tactical applications and sporting use.

What Makes This Different

The salt bath nitride barrel treatment provides superior corrosion resistance and extended barrel life compared to standard phosphate finishes. The A4 flat-top receiver accepts any Picatinny-compatible optics without requiring additional rail systems. This direct impingement system maintains the proven reliability of the M4 platform while offering enhanced durability through upgraded surface treatments.

Key Features

• 16-inch salt bath nitride treated barrel with 1:9 twist rate for 55-77 grain ammunition
• Threaded muzzle (1/2x28 TPI) accepts flash hiders, compensators, and suppressor adapters
• A4 flat-top upper receiver with full-length Picatinny rail for optics mounting
• Six-position collapsible buttstock adjusts from 10.75" to 14.75" length of pull
• 30-round Magpul PMAG included with rifle
• M4-style polymer pistol grip with textured surface
• Chrome-lined bolt carrier group with proper staking and magnetic particle inspection

Field performance centers on the 16-inch barrel length, which provides full powder burn for 5.56 NATO ammunition while maintaining maneuverability in confined spaces. The carbine-length gas system reduces felt recoil and cyclic rate compared to shorter gas systems. Accuracy typically runs 2-3 MOA with quality ammunition, suitable for patrol work, competition, and hunting applications within 300 yards.
