Spike's Enhanced LPK was designed for the end user who demands the most longevity possible out of the parts in their rifles. The core of the Spike's Enhanced LPK is the ST Battle Trigger which is a single stage Mil-Spec trigger, rounded hammer, and disconnector that is Nickel Boron-plated for a very smooth and crisp trigger pull that gets even smoother the more you shoot it. The Battle Trigger is held in place via KNS Gen II Mod II Anti-Rotation pins which keep the hammer and trigger pins from walking out (a problem in some 9mm ARs and full auto M4/M16s) and keeps the pin holes from enlarging and "egg-holing" after years and years of use. Spike's also included an ambidextrous safety selector, ST Billet Trigger guard with set screw, and Ergo grip featuring Spike's Spider logo. The Spike's Enhanced LPK also features a Mil-Spec bolt catch, mag catch, and mag catch button. As well as utilizing Mil-Spec detents, plungers, pins, and springs. The is kit also includes quality spiral roll pins for the trigger guard and bolt catch, as well as a 1/4" allen screw and washer for the Ergo grip.
