Spike's Tactical STR5035R2S ST-15 LE 5.56 NATO 16" Rifle

The Spike's Tactical STR5035R2S ST-15 LE 5.56 NATO 16" rifle represents a purpose-built platform engineered for law enforcement and professional tactical operators who demand reliability under pressure. This rifle is designed for duty use, patrol operations, and dynamic close-quarters engagement where a compact, manageable profile doesn't compromise firepower or durability. The 16-inch barrel length balances terminal velocity retention with maneuverability in vehicle, building, and confined-space scenarios where full-length AR-15 rifles become liability rather than asset.

Built on a proven direct-impingement platform, the Spike's Tactical ST-15 LE features precision-machined components that prioritize consistency and maintainability. The 5.56 NATO chamber delivers proven ballistic performance across commercial .223 Remington and military-grade 5.56 ammunition, ensuring operational flexibility and supply compatibility. At 15.5 pounds, this rifle achieves a practical weight distribution that reduces fatigue during extended wear while maintaining the structural integrity required for sustained-fire engagements and repetitive training cycles. The 42-inch overall length preserves the compact handling advantage of shorter rifles without sacrificing sight radius or rail real estate for optics and accessories.

Law enforcement agencies, tactical teams, and armed professionals benefit most from this configuration, where barrel length directly impacts terminal ballistics and barrel life remains critical for duty longevity. The modular design accommodates industry-standard Picatinny rail systems, allowing integration of lights, lasers, magnified optics, and suppressors without aftermarket modifications. Installation of accessories requires only standard AR-15 compatible mounting hardware, making this rifle immediately deployable for teams with established duty-gear ecosystems. Proper maintenance—cleaning the gas tube and bolt carrier after regular training—ensures reliability that meets law enforcement duty standards.
