The JE Machine Tech PS-ST7B+PS-BTM Mil-Spec Sopmod Stock Combo brings a complete rear-end upgrade to AR-10 and AR-15 builds. Centered around a Mil-Spec Sopmod-style adjustable buttstock and matching 6-position buffer tube, this kit is designed to deliver a solid cheek weld, dependable lockup, and smooth cycling for AR-platform rifles.

This combo includes the Sopmod stock, Mil-Spec buffer tube, carbine spring, buffer, castle nut, and standard end plate, giving builders nearly everything needed for a clean installation. The stock’s wide cheek surface, recoil-reducing buttpad, ambidextrous QD sling mount, and watertight storage compartments make it well suited for training, range use, and general-purpose rifle setups. Thoughtful ergonomics and durable construction reflect JE Machine Tech’s focus on practical design and consistent performance.
