Has anyone fitted one of these themselves? I'm eagerly awaiting the arrival of a Jones adjuster (new) and a mint nearly new 21mm Kick-EEZ from eBay. Just after any tips, i'm pretty handy generally and could work to .001" when I finished my apprenticeship by hand so I don't think it's going to be worth parting with my gun and £££ to have it fitted. I have had a look on Youtube but can't find any video's so might just make one whilst i'm doing it Cheers, Jon.
