UTG PRO Model 4 S2 Mil-Spec Carbine Stock – AR-15/M4 Platform

The UTG PRO Model 4 S2 Stock delivers a solid upgrade for AR-15 and M4-platform rifles, offering improved cheek weld and shoulder contact over standard carbine stocks. The dual-compartment storage design provides practical space for batteries, cleaning supplies, or small tools without adding bulk. Six position adjustability allows shooters to quickly adapt length of pull for different shooting positions, body armor, or seasonal clothing.

Constructed from reinforced polymer with a matte black finish, this mil-spec diameter stock installs on any standard mil-spec carbine buffer tube without gunsmithing. The textured buttpad improves grip on clothing and reduces slippage during recoil. Ambidextrous sling loops accommodate multiple carry configurations. Installation requires removal of existing stock and buffer tube hardware—basic armorer knowledge recommended.
