Notice: 08/12/2015

I will not be taking on any more tuning or servicing work until further notice. I need to carry out some research and development work that I have been putting off for the last few years, due to the lack of free time. I will be finishing off the work on the rifles I currently have on hand, including the ones which are currently booked in, which should take me into February 2016.

On a positive note the development work I am planning will see a number of new and exciting parts, products, guides and services being made available in the eShop and on the website.

The eShop on the website will be open as usual: new parts and products will be added as soon as they become available, making the eShop bigger and better than before.

As soon as I am in a position to start taking on more tuning work I will update the website and the XTX Air Facebook page. Until the R&D is complete I will not be in a position to answer individual enquiries relating to tuning and servicing.

Many thanks for your understanding.

Please bear this in mind when contacting me or chasing me, I work long hours to try to keep everybody happy but there are only so many hours in a day... 

02/04/2014 It has come to my attention that Royal Mail and Parcel Force have decided to prohibit any pressurised vessels. This means buddy bottles, the air cylinders on rifles, rifles with one piece actions that have an inbuilt air cylinder are prohibited.  If you send me your rifle (or parts) and it gets sent to Northern Ireland for inspection and subsequently gets destroyed by RM/PF I will not be held responsible. I use TNT to return rifles that have air cylinders or buddy bottles fitted. 

The temporary work around for people wanting send me their actions is to remove the air cylinder before posting the actions to me. I will use my own air cylinders for testing and setting up the rifle.
