Spike's Tactical ST15 LE Mid-Length 5.56 NATO 16" AR-15 Rifle

The Spike's Tactical ST15 LE delivers law enforcement-grade reliability in a mid-length gas system configuration. This 5.56 NATO rifle combines proven mil-spec components with enhanced ergonomics for professional and civilian applications.

What Makes This Different

The ST15 LE features a mid-length gas system that reduces felt recoil and muzzle rise compared to carbine-length alternatives. The 16-inch barrel provides optimal velocity for 5.56 NATO ammunition while maintaining maneuverability. Spike's proprietary barrel extension and gas block ensure consistent cycling across various ammunition weights and environmental conditions.

Key Features

• Mid-length gas system reduces recoil impulse and extends component life
• 16-inch chrome-lined barrel with 1:7 twist rate stabilizes heavy projectiles
• Mil-spec upper and lower receivers with Type III hard coat anodizing
• M4 feed ramps and barrel extension for reliable feeding
• Standard carbine buffer system with commercial receiver extension

Field performance demonstrates consistent accuracy with match-grade ammunition achieving sub-2 MOA groups at 100 yards. The mid-length gas system cycles reliably with suppressed and unsuppressed configurations. Weather-resistant finishes maintain function in adverse conditions from desert heat to arctic cold. Law enforcement agencies appreciate the balance between barrel length and overall weapon maneuverability.
