We are delighted to welcome back one of the most popular after market improvement products produced for air rifles.
Late 2005 saw the sad demise of Webley and along with it their reputable custom house, Venom. The good news is that Steve Pope is now back in business producing the tuning kits that his name is synonymous with - and we are the official northern agents for them! 

Smoother, quicker, sweeter, more accurate, more refined, better mannered....
Just a few of the descriptions customers give us of their rifles after fitting a V-Mach tuning kit. A V-Mach tuning kit is probably the best seventy five quid you can spend on a spring rifle to improve its performance.
The kit comprises a F1 Powr-Lok spring with a PTFE top hat piston guard and spring guide, C-Form piston seal, pre-compression washers for power adjustment if required, Moly gun grease and Moly gun oil.
The kit is supplied with fitting instructions, and is a viable DIY project for those with a technical mind and some experience of servicing guns. Otherwise, V-Mach recommend employing a gunsmith to fit the kit.
