Kak Ar-15 Lpk Basic Ambi Build Kit$31.99
Availability: In Stock
Building an AR-15 from a stripped lower receiver requires more than just the big parts—you need all the small springs, pins, and controls that make the rifle function. The Kak Industry AR-15 LPK Basic Build Kit is a lower parts kit designed for builders who already have a hammer and trigger in mind. This is the foundation work: everything else your lower needs to cycle, lock up, and run reliably, all mil-spec spec.
This kit skips the trigger group itself, which means you have complete freedom to choose your own hammer and trigger assembly—whether that's a stock mil-spec set, a match-grade option, or a competition unit. You're getting all the supporting springs, detents, pins, and controls: the safety selector, magazine release, bolt catch, buffer retainer, pivot pin assembly, takedown pin assembly, and disconnector spring. Every piece is mil-spec, so it'll play nice with standard AR lowers and uppers.
If you're new to AR building, this kit cuts out the confusion of sourcing individual parts scattered across five different websites. Everything you need (except the hammer and trigger) comes in one box. If you're a seasoned builder with specific trigger preferences, this approach lets you skip paying for parts you don't want and build exactly what you envisioned.
