Spikes Tactical STR5035-R3S ST15 LE | 5.56 NATO | 16″

The Spikes Tactical ST15 LE (STR5035-R3S) is a mid-length semi-automatic rifle chambered in .223 Rem/5.56 NATO built for reliable field use and general-purpose shooting. It uses a 16″ threaded barrel with a 1/2″x28 thread pattern and an A2 flash hider, and features a forged lower with Spikes branding, a Mil‑Spec trigger, and a Spikes M4 stock. For optics, a Vortex Strike Eagle 1-6×24 provides a versatile, sub-$1000 solution that covers short- to mid‑range shooting and pairs well with the rifle’s flat-top upper and typical AR‑style mounting options. Typical applications include range training and practical competition or varmint/medium‑game use where a compact, mid‑length AR platform is appropriate.
