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 cost a 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 auto M4/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.
