JE Machine Tech PS-ST2B+PS-BTM AR-15/AR-10 Mil-Spec 6-Position Collapsible Stock & Buffer Tube Combo - Black

The JE Machine Tech PS-ST2B+PS-BTM Mil-Spec Stock Combo is a matched buttstock and buffer tube set built to true Mil-Spec dimensions for AR-15 and AR-10 platform rifles. Bundling the PS-ST2B collapsible carbine stock with the PS-BTM receiver extension, this combo delivers a drop-in assembly for new builds, replacement of worn furniture, or a spare on the bench.

The PS-ST2B buttstock is molded from high-strength, impact-resistant polymer and rides the familiar M4-style profile, locking securely across all six positions for a stable cheek weld. The mating PS-BTM buffer tube is machined from 6061 aluminum and treated with a hard black anodized finish to resist corrosion and wear from the action spring and castle nut. The stock itself weighs approximately 7.10 oz, keeping the rear of the rifle light and maneuverable.

Engineered to standard Mil-Spec carbine dimensions, the assembly drops onto any AR-15 or AR-10 lower receiver that uses a standard carbine receiver extension. The simple slip-on installation and familiar lever-latch adjustment make the PS-ST2B+PS-BTM combo a practical choice for completing a build or refreshing the furniture on a workhorse rifle.
