  1. Max

    Ordered a 24 inch .527 aluminum barrel for the caliburn and oh boy did I ever get a boost in performance. Shipped reasonably quick and without any damage.

  2. Shawn (verified owner)

    I’m sure it probably works great, but the adapter for the tighter barrels does not work with the Doom Shroud. It won’t let the shuttle travel far enough back for the plunger to catch.

  3. Shawn Eaton (verified owner)

    I previously wrote that it doesn’t work with the doom shroud. I took the coupler off and super glued the adapter to the barrel. It works great so far. I have a brass barrel of the same length and this actual averages about 20fps higher than the brass. I’m digging it now. For reference, the 18″ brass was averaging about 305 – 320 fps. The .495 18″ barrel is averaging 325 – 340 fps.
