KAK Industry AR-15 Missing Parts Kit – Universal AR-15 Lower

The KAK Industry AR-15 Missing Parts Kit contains the small, essential components often left out of standard lower parts kits or lost during builds and maintenance. This kit fills the gaps when you're short a detent, spring, or pin—common issues when assembling or servicing AR-15 lower receivers. It's designed for builders who need specific replacement parts without purchasing a full parts kit.

Includes commonly misplaced or forgotten items like buffer retainer springs, takedown pin detents, pivot pin detents, and their corresponding springs. All components are manufactured to mil-spec dimensions for reliable function. This is a drop-in kit requiring no gunsmithing, though a punch set and familiarity with AR-15 assembly is recommended for installation of detents and springs.
