This mount is designed for and tested on the Diana Chaser, but should work on the Bandit as well. The undermount picatinny rail allows you to mount a laser, flashlight, bipod, or other 21mm picatinny accessory. It is 3d printed in ABS plastic in one piece. It uses two stainless steel socket cap screws and nuts to clamp tightly onto the CO2 tube and barrel without damaging the airgun.

To install it:

  1. Remove the 3 M4 set screws that secure the barrel and remove the barrel
  2. Loosen the 2 socket cap screws on the Barrel Band if not done already
  3. Slide the Barrel Band onto the larger CO2 tube(you may need to remove the CO2 cap)
  4. Reinstall the barrel, passing it through the smaller hole in the band
  5. Rotate the barrel into the proper position and tighten the 3 set screws
  6. Tighten the 2 socket cap screws in the barrel band(just make them snug, they do not need to be very tight)
  7. Reinstall the CO2 and cap if they were removed

This mount should be compatible with the Bandit as well, but I’ve only tested it on the Chaser. If you buy it for one of those airguns and it doesn’t work out just let me know and I’ll be happy to refund you or make something that works.

    I mounted one of these on my Diana Storm Rider so I could mount a bi pod. You couldn’t ask for anything better. It fit the gun perfectly, did not pull the barrel down at all. All I had to do was remove the barrel after removing my scope and install the band. Took about 3 minutes. Re-zeroed the scope and was in business. This is something that I have been looking for, for a long time. Kudos to you Terry, great product!! I already other products from you so I shouldn’t have been surprised when this work so well.

    The barrel band with picatinny rail works great with the Buck-Rail bipod that I just purchased and attached to my Diana Chaser rifle and it works! This is another fantastic product from Buck-Rail!

    The one thing that always held me back from getting the diana chaser was the gap between barrel and air tube. This barrel band fixes that issue and solidifies the barrel amazingly. No flex at all. Nice tight fit. And the ability to add something with a picatinny section is a great addition.

    Yes a barrel band with picatinny rail on the bottom for the Diana Chaser. Also added the Buck-Rail bipod. Great products at awesome prices. I will say i had a heck of a time getting the band on. Very tight on the barrel & CO2 tube. Keep the great products coming Buck-Rail…………
