Description
Seamlessly adapt the Magpul™ UCS folding stock to your Springfield Kuna. Our adapter is light weight, low profile, and integrates the UCS stock directly into the rear trunnion of the Kuna by removing the lengthy 1913 interface completely. The UCS stock is unique in that the hinge can be reversed to fold either left or right. Our stock adapter is machined from billet 6061T6 aluminum and hard coat anodized to MIL-A-8625. The Magpul™ UCS stock is polymer, and includes two cheek risers (0.50ʺ and 0.75ʺ).
Note: HBI stocks and braces for Springfield Kuna are made to factory spec, and are compatible with 100% of factory lower receivers. They may/may not directly fit aftermarket lower receivers. If using a Nexus aluminum lower receiver it may be necessary to remove about .005-.010″ of material from the inside of each “fork” flange on their lower in order to mount one of our Kuna stock adapters.
