This is a quick video to show how to install the HuMa R-10 regulator.
You need to make sure your rifle is not loaded and does not have a magazine fitted.
Remove the buddy bottle following the normal bottle removal procedure.
Remove the single cap head screw from the centre of the toast rack with a 5mm Allen key.
Remove the anti-tamper cap on the regulator (separate instructions will be sent with the regulator).
Remove the brass regulator body from the regulator block.
Make sure the all the parts and O rings have been removed but leave the little grub screw in the hole.
Clean out the hole.
Screw in the pre-set HuMa regulator.
Refit the regulator block to the action.
Refit the buddy bottle.
Chrono your rifle to make sure it is legal with a selection of pellets.
Adjust the power if necessary (separate instructions will be sent with the regulator).
Keep it legal and enjoy trouble free shooting!
The regulators are available from my website www.xtxair.co.uk. They will work in sub 12ftlbs rifles and in FAC rifles.
Please note that if your R-10 has been blueprinted by John Bowkett these regulators will not work because of the oversize screw he fits to the regulator block when carrying out a blueprint. The larger screw breaches the O ring seal on the HuMa regulator. If you want to fit a HuMa regulator to a blueprinted rifle you will have to replace the regulator block.
