The JE Machine Tech SOPMOD Stock Combo (brand part no. PS-ST7B+PS-BTM) pairs a SOPMOD-pattern collapsible stock with a matching mil-spec buffer tube, taking the guesswork out of building a compatible stock setup from scratch. The SOPMOD design adds an adjustable cheek riser for a more consistent cheek weld with optics mounted higher above the bore, along with internal storage compartments in the buttpad for small spare parts or a cleaning kit. Because the stock and tube are sold together at matching mil-spec diameter, fit between the two is guaranteed. JE Machine Tech builds the combo for AR-15/M4 owners who want the SOPMOD stock’s added features without separately sourcing a compatible tube.

Key Specifications

• Includes a SOPMOD-pattern stock and matching buffer tube sold together as one combo.
• Features an adjustable cheek riser, improving cheek weld consistency with raised optics.
• Has internal storage compartments in the buttpad for small parts or a cleaning kit.
• Built to mil-spec diameter on both pieces, guaranteeing correct fit.
• The stock ships uninstalled from the tube, so final assembly is a simple two-piece slide-and-pin fit typical of mil-spec AR builds.
