Ultradyne UD6 CHS Combo Right-Hand Stock Assembly – AR-15/M4

The Ultradyne UD6 CHS Combo Stock Assembly delivers a complete, tunable stock solution for AR-15 and M4 platforms. Designed for shooters who demand precise length-of-pull adjustment and consistent cheek weld, this right-hand configuration combines a mil-spec carbine buffer tube with Ultradyne's ergonomic stock body. The assembly reduces perceived recoil through improved shoulder contact and allows faster target reacquisition in rapid-fire strings.

Constructed from reinforced polymer with a black anodized aluminum buffer tube, the UD6 CHS installs on any mil-spec lower receiver using standard carbine components. The stock features six adjustable positions and textured contact surfaces for secure mounting in field conditions. Right-hand configuration optimizes cheek weld and sighting alignment for right-eye-dominant shooters. Kit includes buffer tube, stock body, castle nut, and end plate for complete installation.
