This custom build rifle starts with a Spike's Tactical ST-15 lower receiver and an aftermarket upper, configured for direct-impingement semi-automatic operation. It is marked MOD ST-15 with the Spike's spider rollmark on the magwell and includes a forward assist, shell deflector, and ejection-port cover.
