Spike’s Tactical Enhanced Lower Parts Kit is engineered for shooters who prioritize durability and longevity in their AR platform builds. At the heart of this kit sits the ST Battle Trigger—a single-stage Mil-Spec trigger with a rounded hammer and disconnector, all Nickel Boron-plated to deliver a smooth and crisp trigger pull. The trigger assembly is secured with KNS Gen II Mod II Anti-Rotation pins that prevent hammer and trigger pin migration and protect pin holes from enlarging and “egg-holing” over extended use.
The kit rounds out with an ambidextrous safety selector, ST Billet Trigger guard featuring a set screw, and an Ergo grip with Spike’s Spider logo. All remaining components—Mil-Spec bolt catch, mag catch, mag catch button, detents, plungers, pins, and springs—meet military specifications. Spike’s Tactical includes quality spiral roll pins for the trigger guard and bolt catch, plus a 1/4″ allen screw and washer for the Ergo grip. Made in the USA.
