davewh100 Posted December 4, 2021 Report Share Posted December 4, 2021 morning members, the wildcat evolution mods have a bush that screws in to the back some times these need drilling out to fit the right size barrel, if it's an 18mil barrel how much more would you give it thanks dave Quote Link to comment Share on other sites More sharing options...
London Best Posted December 4, 2021 Report Share Posted December 4, 2021 If I understand the question correctly, about one half to one thousandth of an inch. A precision boring job not a drilling job! Quote Link to comment Share on other sites More sharing options...
wymberley Posted December 4, 2021 Report Share Posted December 4, 2021 May pay to contact the makers as they say a maximum barrel dimeter of 25mm. Quote Link to comment Share on other sites More sharing options...
rangey Posted December 4, 2021 Report Share Posted December 4, 2021 Got 3 wildcats and never use the Bush... All it does is mark the barrel Quote Link to comment Share on other sites More sharing options...
Windswept Posted December 4, 2021 Report Share Posted December 4, 2021 IIRC it's only there to stop you cross threading the threads, it shouldn't ever touch the barrel. I'd email them and ask if you're unsure, when I got mine they told me "leave a 4 thou clearance which is just enough to get a piece of paper through" Quote Link to comment Share on other sites More sharing options...

Dougy Posted December 5, 2021 Report Share Posted December 5, 2021 Use mine, but its clear of the barrel, cross the threads and you'll soon start to cuss. (stainless barrels so no bluing to rub off) Quote Link to comment Share on other sites More sharing options...
