I picked up a new Henry single shot today in 460 Bushmaster to use in IL deer season. I had previously ordered the weaver 82 scope base but discovered that I will have to remove the rear sight to install it and would rather not do that.

I did a forum search and picked up a couple of other options. One is the Leupold 56515 rail and the other I found in a picture from SCGunNut but was not identified.

I think that with the Leupold I will still have to remove the sight, anyone else use this base and know for sure if that's the case?

I'll PM SCGunNut to see if he can enlighten me on the other mount.

Anyone know of any other options?
