Sutcliffe Electronics first produced Gasgun conversion kits in 1985. They are still available with the current MkIV electronics modules.
The kit provides an economic way of obtaining a new Gasgun, with a year’s guarantee, without the expense of buying a new barrel. It is easy to install using the normal tools found in a farm workshop, on almost any propane gasgun. The conversion taking about an hour.
The kit consists of the same weatherproof housing as the KITGUN, electronics module, long reach spark plug, plug mounting plate, all necessary leads, and full instructions. It is assumed that the high pressure regulator, gas pipe and fittings from the old gun are still serviceable.
