Description
This mount is designed for and tested on the Diana Chaser and Airbug, 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. It is available with a single bottom rail or with the additional side rails. Just choose your option before adding to cart.
To install it:
- Remove the 3 M4 set screws that secure the barrel and remove the barrel
- Loosen the 2 socket cap screws on the Barrel Band if not done already
- Slide the Barrel Band onto the larger CO2 tube(you may need to remove the CO2 cap)
- Reinstall the barrel, passing it through the smaller hole in the band
- Rotate the barrel into the proper position and tighten the 3 set screws
- Tighten the 2 socket cap screws in the barrel band(just make them snug, they do not need to be very tight)
- Reinstall the CO2 and cap if they were removed
Recommended installation by Buck-Rail is to remove the barrel from the breech.
Guess that way would be less fiddly, easier, safer, and use fewer tools, but I chose to remove the moderator and front sight since I had planned on upgrading the moderator later anyway to either the Buck-Rail Diana Chaser M10 x 1.00 Threaded Suppressor or a 1/2 x 20 adapter.
You will need to carefully use a heat gun to heat up the sides of the moderator ( plz don't direct the heat down the muzzle end like some suggest --or you will melt your breech seal!) to loosen the Loc-Tite thread locker glue so the moderator will unscrew. Then with a hammer &a small block of wood,tap the plastic front sight ( that you were careful not to melt!) off towards the muzzle end.
Loosen the screws of the Buck-Rail barrel band, slide on, and reassemble.
Once installed, the Buck-Rail Tri-Rail barrel band fits perfectly, really supports barrel, and allows attachment of a bipod and two other accessories like a laser or light--AWESOME !
Thank you

One note; I did order a band with one rail on the bottom before I knew Terry made a three rail one. It did seems a tad wider, did not measure and it may be my China bi pod but will have to modify something get it to clamp tighter. Problems installing? just spread it lightly with a screw driver and slip on..Tighten evenly and slowly . Clean the burr off barrel to fix the ruff pellet feed with a #953 dremel bit
Keep on making cool stuff for use air gun nuts!
