KAK M16 A2 RIFLE BUTTSTOCK KIT

Description

The KAK Industry A2 Buttstock Kit gives AR-15 builders a straightforward path to a fixed, rifle-length stock setup without hunting down individual components. Everything required for a complete installation ships together: a polymer A2 stock with a built-in storage compartment, an A2 extension tube, a chrome silicon A2 rifle buffer spring, an A2 spacer, and an assembly screw. Having matched components from a single source matters more than it might seem — the spring rate, buffer mass, and tube dimensions are sized to work together, which removes the guesswork of mixing parts from different runs.

The fixed A2 geometry puts the shooter’s eye at a consistent distance from the optic or iron sights every time the rifle comes to shoulder. That repeatability is the core argument for a fixed stock over an adjustable one, and it comes at the cost of configurability — length of pull is set, so fit depends on the shooter’s build and gear. For standard-frame adults shooting with light clothing, the A2 pull length has been the military reference point for decades, which means holsters, slings, and accessories designed around that standard translate directly.

The polymer stock keeps weight down compared to older aluminum-reinforced designs, and the storage compartment in the toe of the stock is sized for a cleaning kit or spare parts. KAK manufactures this kit in the USA. At its price point it is a practical choice for a retro-style build, a budget rifle, or replacing worn original furniture without overcomplicating the parts list.
