The Leapers Inc. UTG Pro AR15 S4 Mil-Spec Stock in Flat Dark Earth gives your AR platform a combat-ready cheek rest setup without the bulk. Built from impact-resistant polymer with exacting tolerance controls, this mil-spec stock delivers the tight, rattle-free fit that matters when you're running drills or heading downrange. The FDE finish pairs well with modern rifle setups and blends naturally in field conditions.
What sets the S4 apart is its thoughtful ergonomic design. The slanted cheek rest geometry helps you index consistently behind your optic, while the removable extended cheek rest insert lets you dial in the right height for your shooting style—carrier-heavy kit, low-profile setup, or anything between. Four position adjustability spans 4.28 inches of usable length of pull, so whether you're in a plate carrier or running light, you'll find a comfortable shouldering position. The reversible sling swivel housing and standard sling loop integrate seamlessly into your rifle's support system.
Rubberized butt pad absorbs recoil and grips your shoulder under load. Mil-spec compatibility means it drops right onto any AR-15 with a standard tube, and the compact footprint keeps your rifle handy in tight quarters—vehicle, barricade, or confined space work. This is genuine UTG Pro quality: engineered for heavy use, finished to last, and designed by people who actually shoot.
