Overview

HB Industries' Kuna UCS Stock pairs the Magpul UCS (Utility Carbine Stock) with an HBI-machined adapter that replaces the Kuna's 1913 interface and bolts to the rear trunnion directly. The adapter is 6061-T6 aluminum with a MIL-A-8625 Type 3 hardcoat anodize. Assembled weight is 28 oz.

The Magpul UCS component gives 10.8 to 14.0 inches of length-of-pull adjustment, includes two cheek risers (0.50-inch and 0.75-inch), and folds either left or right because the hinge is reversible. HBI sells the kit at $276. Per HBI, all NFA rules apply if installed on a pistol-configured Kuna.
