Tuning clamping around air bottle

I know what you’re looking for. They make those pic rails in a scope ring form, to add a pic rail on top of your scope for a laser or torch. If you’re wanting to mount a torch or laser, watch out for barrel droop should you find one to mount on a barrel. Stuart at smwengineering.uk.com has barrel to air tube clamps and a couple of barrel to bottle clamps with side and bottom pic rails added during the 3D manufacture. Check out his site.
