The JE Machine Tech A-Frame Skeleton Stock (brand part no. PS-ST8B) trims weight off an AR-15 build with an open, cutout frame in place of a solid stock body. It is built to mil-spec diameter, so it fits standard mil-spec buffer tubes without needing a matched proprietary tube. The skeletonized A-frame design cuts away material that a solid stock would otherwise carry, shaving weight from the rear of the rifle while still providing a stable cheek weld and shoulder point. JE Machine Tech builds this stock as a straightforward, budget-friendly way to lighten an AR-15 or refresh an older build without moving to a premium adjustable stock.
