cribmaster Posted October 3, 2012 Report Share Posted October 3, 2012 hello people can anybody tell me the screw size of the front bead size of a hatsan escort semi and a winchester sx3 thanks Quote Link to comment Share on other sites More sharing options...
Mikaveli Posted October 3, 2012 Report Share Posted October 3, 2012 Hatsan Escort (PS) now come with 2 beads - one metal / brass bead about 3mm in diameter and you also get a fibre optic bead (about 2mm) with 3 coloured inserts. Beads are completely interchangeable - so fleebay etc. can be a good source if the OEM kit doesn't suit you. Quote Link to comment Share on other sites More sharing options...
hawkfanz Posted October 3, 2012 Report Share Posted October 3, 2012 like mikaveli says have a look at ebay sporting goods/hunting for sight beads dont no thread size for yours but you,ll find em there. Quote Link to comment Share on other sites More sharing options...
Gordon R Posted October 3, 2012 Report Share Posted October 3, 2012 Normally 2.6mm or 3.3mm. If you are going on to E*ay - check Claymantaurus - I think he is on Pigeonwatch - about half price of the rest. Quote Link to comment Share on other sites More sharing options...
cribmaster Posted October 4, 2012 Author Report Share Posted October 4, 2012 thanks will have a look have seen some on there just needed to know what screw size to buy Quote Link to comment Share on other sites More sharing options...
clayman Posted October 5, 2012 Report Share Posted October 5, 2012 Thread size is not really an issue. The std size is 2.6mm - and the 24 types on eBay are all this thread. Just a few guns have 3mm or 3.2 - but if your gun does have the larger size the solutions are simple. Either use a gap filling adhesive, and epoxy, to secure it in the hole - or take a piece of insulation off copper wire, thread the 2.6mm bead into it, and then thread the whole thing into the gun hole. You can muck about with PTFE tape as a thread gap filla, but the insulation tube solution is easiest. Claymantaurus Quote Link to comment Share on other sites More sharing options...
