    All receiver extensions are not equal, and the INTRAFUSE tube is second to none. The best Mil-Spec extension available today, the tube is impact extruded, producing a much stronger part.
    This is done using 7075 T6 Aluminum, the same material as most AR receivers. INTRAFUSE didn t skip any steps on the finishing process either. The inside of the tube is coated with Mil-Spec dry film lubricant that not only keeps the action quieter; it reduces metal-on-metal contact, extending the service life of your buffer. While most other tubes are anodized or have no finish, the outside of the INTRAFUSE tube is grit blasted to leave a non-reflective surface, then coated in Mil-Std 171 Lusterless Black for a smooth matte finish.
