UTG PRO Model S4 Mil‑Spec Stock Black

Elevate your rifle’s performance with the UTG PRO Model 4 S4 Mil-Spec Butt Stock RBUS4BMS, proudly designed and built in the USA. Crafted from ultra-tough, impact-resistant polymer in a sleek matte-black finish, this sub-compact powerhouse brings professional-grade comfort, control, and confidence to every mission, match, or range day.

At just 7.2 ounces and a scant 4.28 inches long, the Model 4 S4 merges featherweight agility with rock-solid durability. Its minimal-bulk profile seamlessly integrates with SBR platforms, super-slim handguards, and compact builds—delivering a no-nonsense upgrade that won’t weigh you down. Four adjustable length-of-pull positions let you dial in the perfect fit for quick transitions, faster follow-up shots, and seamless shoulder acquisition over plate carriers, chest rigs, or layered gear.

UTG’s obsessive attention to detail shows in every contour: an ergonomic slanted cheek rest aligns your eye with iron sights or optics in a flash, while a removable 5.51-inch extended insert gives you custom-tuned cheek weld for high-power scopes or backup red dots. A cushy rubberized butt pad soaks up recoil and shields against slippage, keeping your shots on target and your shoulder free of bruises. When it’s time to sling up, switch between left- or right-handed sling swivel housings or grab the standard sling loop for classic attachment—true ambidexterity without compromise.

Built to outperform in harsh environments and abuse-resistant under the strictest mil-spec standards, the UTG PRO Model 4 S4 marries cutting-edge manufacturing tolerances with a lightweight, low-profile design that never gets in your way. Whether you’re slicing through close-quarters drills, staking out a distant landmark, or simply cruising through your next training session, this buttstock is your ticket to faster, smoother, more confident handling.

Join shooters worldwide who trust Leapers UTG’s legacy of innovation, excellence, and rock-solid support. Upgrade your platform with the Model 4 S4 and experience the difference that precision-engineered comfort and modular versatility can make for your shooting lifestyle.
