tarawa, I didn't like the ones they sent with the gun so I cleaned up the dovetails on the gun and installed some different rings but in order to try and get the scope out a little further, I machined the dovetails clear on out to the front end. That didn't work out well because the front mount kept sliding off the front of the dovetail so I cross drilled it right through the center of the dovetails and installed a crosspin to stop it from moving forward. It worked out well enough and I think it makes the mount look better. I wish I could remember the brand of rings I used but I'm sorry, I don't remember. As I recall, they were nothing special but they have held up well. Bob H.
