rear sight pinned, set screw????
« on: April 21, 2011, 01:00:49 AM »
The rear sight on my PCR has what looks like a set screw. However, it does not seem to take an allen wrench. Whatever it is, does it have to be removed/loosened before the rear sight can be moved or removed. Is so, is there a way to loosen "set screw"? Thanks for any info.

May be a star drive screw. Sometimes they even have a pin in the center of the hole. They look a lot like allen wrench holes.

I'm guessing it's a roll pin (CZ's term coiled pin) which would be tapped out with a brass pin punch. Careful with the brass punch as it will rub off on the metal.

Looking at the exploded picture, there doesn't seem to be a pin or set screw for the rear sight.

Unfortunately, I don't know how to do digital pictures. But there is a hole in center of my rear sight.
 
Is the exploded picture you are looking at in digital format? If so I would appreciate your linking, transmitting, whatever. You can tell I am not big with computers. Thanks.

The exploded diagram covers like 5 different models, but the PCR is among them.

Thanks. It could just be a hole. Don't know why there would be a hole in rear sight without screw or pin, but who knows.
 
I tried to call CZ today, but they were closed for Good Friday. Will try next week.
