KAK Industry AR-15 Lower Parts Kit No FCG – AR-15 Platform

The KAK Industry AR-15 Lower Parts Kit provides all the small parts needed to complete a stripped AR-15 lower receiver, excluding the fire control group. This configuration allows builders to install their preferred trigger assembly while supplying everything else: magazine catch, bolt catch, takedown pins, trigger guard, safety selector, pistol grip, and associated springs and detents. Ideal for custom builds where trigger choice is a priority.

Manufactured from mil-spec steel and aluminum components with a black oxide finish on steel parts. All parts are dimensionally correct for standard AR-15 lower receivers. Installation requires basic gunsmithing tools and familiarity with AR-15 lower assembly—proper detent installation is critical to prevent loss of small parts under spring tension.
