I have a combat elite, which I purchased new around 1996. I need to replace the rear elevation screw but don't know if the rear sight is an Elliason or an Accro. The blade sits in a dovetail on the rear of the sight and the elevation screw has a detent
Frank, either way , the screw should be a 6x48 tpi (thread per inch), with a threaded shank approx .285" in length (9/32?) Yes, must have the 'notches' under the head of the screw and some of the early ones had an 'indicator' mark (groove) perpendicular to the screws 'slot'. This was also for the 'Micro' sights as well, so they will interchange, I use whatever is available or I can find. Rugers will work too, but the new ones are a bit too long.
