Had an Aimpoint t1, then a vx6 1-6, and now a Burris Fastfire 3 on my 1895. I don't care for scopes mounted on the receiver on lever guns. If you don't need magnification I would consider a ff3 on a burris mount.

Another option is the xs scout mount. Puts a ier scope over the barrel. I have a 444ss setup this way and am a fan.
