These are fab guns, very accurate and light.

There were three marks made, the first two had two piece stocks and the third had one piece. The mk2 had a barrel support or should I call it a stock support. A target version was also available with adjustable stock + a 6lb version.

Servicing is pretty easy, anti tamper only came in on the mk3. A worthwhile mod is to fit a regulator. Lanes do two regulators, one internal the other external. They also do a quick fill and pressure guage, very handy to keep an eye on. Huma also do the same.

As previously stated removing the end caps of the cylinder can be a pain as they are very tight but only necessary if you fit a reg or quick fill. Lanes do a cylinder release nut to facilitate in removal. Wrap the cylinder up well and clamp in a vice an fit lanes nut over the cylinder and remove with 12"+ adjustable wrench. A quick shock tap usually breaks the seal. I have never come across thread seal though.
