JR FIREARMS Posted December 30, 2020 Report Share Posted December 30, 2020 Seen a few Sabattis lately where the picatinny rail screws have stripped out the action under recoil. I have found various causes for this which ultimately are all down to quality issues. It’s a fairly simple fix, especially with the CNC mill. It’s a case of measuring hole spacing, a quick CAD model, then boring out and threading for larger threads, In this case 8-40. The rail also needs machining to allow fitment of the larger screws.

JR FIREARMS Posted January 2, 2021 Author Report Share Posted January 2, 2021 Scope base screw repair and upgrades are helically boted and thread milled for better accuracy and tolerance, then checked to ensure they are within specification. Available in M4 x.7 and 8-40. Quote Link to comment Share on other sites More sharing options...
Woodlander Posted January 22, 2021 Report Share Posted January 22, 2021 I think this is a common upgrade on Remmy actions. Quote Link to comment Share on other sites More sharing options...
Fox Tales Posted January 22, 2021 Report Share Posted January 22, 2021 Would it be possible to correct misaligned holes using this method ? Quote Link to comment Share on other sites More sharing options...

Yes it’s an ideal way of solving that problem. The boring of the hole and thread milling mean the old thread will not influence the new ones, which is what can happen when using the traditional method of drilling and tapping, as the drill and tap will want to follow the old thread.
