Helping my local CLEO rehab a M37 slug barrel, it's marked "Police Duty" or something similar.

Has a fixed leaf rear and the front ramp sight has a push button in front of the blade insert. Pushing down on the button allows you to slide the blade towards the muzzle, over the button, and completely remove it. The insert is a Dayglo orange. The only mark on the ramp sight is "Patent Appl."

Anyone know who made this type of sight?


thanks,

Rob

Something like this Raybar?

Just like that Raybar, thank you.
