Spikes Tactical ST-15 LE STR5025M4S | 5.56 NATO | 16″

The Spikes Tactical ST-15 LE M4 Carbine (STR5025M4S) is built to meet law-enforcement duty requirements, featuring a chrome moly vanadium, chrome-lined, threaded barrel with an A2 flash hider and a Mil-Spec phosphate finish on key components. The forged 7075-T6 lower includes Spikes’ low-shelf geometry and RDIAS compatibility, paired with a six-position Spikes M4 stock and an ergonomic pro grip for predictable handling. The rifle ships with Magpul MBUS rear sight and an A2 front sight; its gas tube and charging handle carry corrosion-resistant finishes for long-term reliability.

For an optic that complements the ST-15 for both close-to-mid range duty and competition use, consider the Vortex Strike Eagle 1-6×24, which offers a versatile low-power variable platform and a reticle suited to rapid target engagement while remaining under typical pro-level optic budgets. Typical applications for this carbine include law enforcement/duty use and competitive shooting or range training.
