The Aero Precision Enhanced Pistol Tube (brand part number APRH100302C) is a Black 7075-T6 aluminum receiver extension built for AR-15 and AR-10/M5 (.308) pistol builds. Aero Precision cuts a slot into the threads so the tube works with a standard end-plate and castle nut setup, a detail pistol builds rely on since they use an arm brace or QD end-plate assembly instead of a fixed stock. It fits standard AR15 and M5 (.308) lower receivers, giving builders a reliable, correctly toleranced foundation for a pistol-format upper. Note that the tube ships alone, with no end-plate, buffer, or spring included.
