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