Have you made adjustments to lighten the trigger? On both my Crown MK2 rifles I have made adjustments to really lighten the trigger and on both rifles I lost the ability to have a functional safety. The rifles are still very safe and the triggers work as they should. I don’t use safeties on rifles and I’m a firm believer in the safety between my ears. I never carry a rifle when it is loaded.

Hi, That is a standard M3x6 grub screw. You can get an entire kit of metric grub screws from Amazon for cheap. You simply replace the M3x6 with and M3x8 or an M3x10. Cheers, Greg
