The Spike's Tactical Enhanced AR-15 Lower Parts Kit (5.56) is a high quality, durable Lower Parts Kit with several upgrades that would costa lot more if ordered separately. The core of the Enhanced LPK is the single stage ST Battle Trigger featuring a rounded hammer and disconnector that's plated with Nickel Boron to give the Battle Trigger a very smooth and crisp trigger pull that gets even smoother the more you shoot it. KNS Gen II Mod II Anti-Rotation pins keep the hammer and trigger pins from walking out (a problem in some 9mm ARs and full autoM4/M16s) which prevents the pin holes from enlarging after years and years of use. Other upgrades include an Ambidextrous Safety Selector, a Billet Trigger guard with set screw, and an Ergo grip featuring the Spike's Tactical Spider logo.
