Spikes Tactical ST-15 LE 5.56 NATO 16" Mid-Length AR-15 Rifle

The Spikes Tactical ST-15 LE delivers professional-grade reliability in a mid-length gas system configuration optimized for law enforcement and civilian applications. This 5.56 NATO/.223 Remington rifle combines proven direct impingement operation with enhanced ergonomics and durability standards.

What Makes This Different

The mid-length gas system provides smoother cycling and reduced felt recoil compared to carbine-length alternatives. Spikes Tactical's enhanced bolt carrier group features improved materials and tighter tolerances than mil-spec standards. The 16-inch chrome moly vanadium barrel delivers consistent accuracy while maintaining the compact profile required for tactical applications.

Key Features

• Mid-length gas system reduces bolt velocity and extends component life
• 16-inch chrome moly vanadium steel barrel with 1:7 twist rate
• Hard coat anodized Type III finish resists corrosion and wear
• Six-position collapsible stock adjusts from 10.75" to 14.25" length of pull
• Flat-top upper receiver with full-length Picatinny rail
• Enhanced bolt carrier group with properly staked gas key
• Standard AR-15 magazine compatibility accepts STANAG pattern magazines

Field testing demonstrates consistent sub-2 MOA accuracy with quality ammunition. The mid-length gas system cycles reliably with both 55-grain and 77-grain projectiles across temperature extremes. Law enforcement agencies report excellent durability through extended training cycles and adverse conditions. The rifle functions reliably suppressed or unsuppressed with appropriate ammunition selection.
