Springfield Armory Kuna Adjustable Folding Rifle Stock Black

The Springfield Armory Kuna adjustable folding rifle stock is the factory-spec buttstock engineered specifically for the Kuna platform. If you're running a Kuna and want to maximize portability without sacrificing a solid cheek weld, this is the stock that bridges compact storage and repeatable shooting comfort. The push-button folding mechanism collapses the stock cleanly for vehicle carry, pack transport, or tight shooting positions, then deploys just as smoothly when you're ready to shoot. Whether you're working shorter ranges or dialing in a precision rig, the four-position adjustability lets you dial in exactly the length of pull your frame and shooting style demand.

The rubberized butt pad grips your shoulder, kills recoil slap, and keeps the rifle planted during consecutive shots. Dual QD sling sockets give you flexibility to rig the stock for your preferred carry method—whether that's a two-point, single-point, or hunting configuration. The stock attaches directly to the Kuna receiver for a clean, secure fit and goes on without receiver modification, preserving the original handling and balance the platform was designed around.

A critical note: Installing this stock may trigger NFA regulations and 922(r) compliance requirements depending on your Kuna's configuration and origin. Before you install, consult a qualified firearms attorney to confirm your build remains legal in your jurisdiction.
