KAK Industry AR-15 LPK Features The KAK Industry AR-15 LPK includes the essential small parts needed to complete a stripped lower receiver from the bolt catch kit and magazine catch kit to the takedown pin pivot pin and buffer retainer pin with their respective detents and springs. The ambidextrous selector detent and spring give shooters the option to run the safety on either side of the receiver a useful feature for left hand shooters or dual role builds. Hammer and trigger pins along with the hammer trigger and disconnect springs complete the fire control group so builders are not left searching for missing small parts. KAK Industry designed this kit to include just the basics needed for a reliable functioning lower. Builders should apply blue Loctite to the ambidextrous selector screw threads during assembly after degreasing ensuring the selector stays secure through recoil cycles. Because the kit focuses on the essential components rather than bundling in extras a builder may not need it keeps the cost down for those working within a budget. This kit pairs well with any stripped AR-15 lower receiver and complements a wide range of stocks grips and trigger upgrades added separately. For anyone assembling a custom AR-15 from a stripped receiver the KAK Industry LPK is a dependable foundation to build from.
