very cool

I had one installed on a new Winchester 1895 in .405 Winchester and it looks and functions well. Right about the front sight, it needs to be a little over a .5 tall. you can also get the aperture taped and use Marble eyepieces.
Should be a download on their site about how to install which explains everthing.
