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

The UTG PRO Model 4 S2 stock kit delivers a solid upgrade for mil-spec buffer tube AR-15 and M4 platform rifles. This complete replacement stock enhances shooter control with six adjustable positions and an anti-slip rubber buttpad that reduces felt recoil while maintaining a secure shoulder weld during rapid strings or extended shooting sessions.

Constructed from reinforced polymer with a mil-spec diameter receiver extension interface, this stock kit installs directly onto standard mil-spec carbine buffer tubes without additional adapters. The textured cheek weld area provides consistent face placement for optic alignment, while dual QD sling swivel slots offer ambidextrous mounting options. Includes everything needed for installation: stock body, anti-slip rubber buttpad, and mounting hardware.
