The Spikes Tactical Enhanced Lower Parts Kit is an AR-15 lower parts kit built for shooters who want durable internal and control components. Its centerpiece is the ST Battle Trigger, a single-stage Mil-Spec trigger with a rounded hammer and disconnector, finished in Nickel Boron for a smooth, crisp pull.

The kit includes KNS Gen II Mod II anti-rotation pins to hold the hammer and trigger pins in place, an ambidextrous safety selector, an ST Billet trigger guard with set screw, and an Ergo grip. Mil-Spec bolt catch, magazine catch, and detents, plungers, pins, and springs are included. The kit is finished in black and made of 7075 T6 aluminum with steel and polymer components.
