The core of this build is a Spike's Tactical ST-15 lower receiver with pictogram-style selector markings, paired to a VooDoo Innovations-marked flat-top upper. A custom engraved dust cover features a skull motif with U.S. flag panels, adding distinctive receiver details. The lower's serial marking shows an SBR- prefix.
A Midwest Industries free-float quad-rail handguard with T/R/B index markings provides continuous rail space and clear position references. Polymer flip-up front and rear sights serve as backup irons when used with the red dot. The flat-top upper offers straightforward mounting for the included optic and other rail-mounted accessories.
The 16-inch M4/Government profile barrel is threaded and equipped with a standard A2 flash hider. The rifle uses a direct-impingement gas system. Magpul furniture includes a CTR 6-position carbine stock and MOE pistol grip, with a 13.0-inch length of pull for an adjustable, familiar fit.
Controls and internals are set up for clean operation: an ambidextrous extended-latch charging handle improves access, the bolt carrier group carries a chrome/nickel finish, and the flat, light trigger promotes a crisp, consistent pull. A detachable STANAG-pattern magazine system is included, with a 40-round extended magazine shown.
Optics are handled by a Bushnell red-dot sight with a red reticle and tube-style body, mounted on a Picatinny riser to elevate the sightline. Combined with the backup flip-up sights, the setup is ready for immediate use while allowing simple adjustments to suit user preference.
