Black Rain Ordnance BRO-SSPSMK Spec 15+ 5.56 NATO 16" Rifle

The Black Rain Ordnance BRO-SSPSMK Spec 15+ delivers precision engineering in a smoke-finished AR-15 platform chambered in 5.56x45mm NATO. This rifle combines proven reliability with modern modularity for competitive shooting and tactical applications. The 16-inch barrel length provides optimal velocity while maintaining maneuverability in confined spaces.

What Makes This Different

Black Rain Ordnance builds this rifle with a proprietary upper and lower receiver set featuring enhanced tolerances and corrosion-resistant coatings. The 15-inch slim M-LOK handguard extends nearly to the muzzle, providing maximum real estate for accessories while reducing overall weight compared to quad-rail systems. The smoke Cerakote finish offers superior durability against environmental elements while maintaining a professional appearance.

Key Features

• 16-inch chrome-moly vanadium steel barrel with 1:7 twist rate for heavy bullet stabilization
• 15-inch free-floating M-LOK handguard with anti-rotation barrel nut system
• Magpul MOE grip and carbine stock for proven ergonomics and adjustability
• Smoke Cerakote finish rated for 2,400+ hours salt spray resistance
• Standard AR-15 magazine compatibility with 30-round Magpul PMAG included
• Mil-spec trigger group and bolt carrier group with proper headspacing
• A2 flash hider with 1/2x28 threading for suppressor compatibility

Field testing demonstrates consistent sub-2 MOA accuracy with quality ammunition, while the gas system cycles reliably with both 55-grain and 77-grain projectiles. The M-LOK attachment system accommodates bipods, lights, and laser devices without adding unnecessary bulk. Weather sealing at critical junctions maintains function in adverse conditions, making this suitable for duty use, competition, and recreational shooting.
