I'd just go with the EoTech or other Holosight. I've used the Bushnell version on a 10/22 and on a Bushmaster flattop. The 1 MOA dot and 65 MOA circle is perfectly good for me (uncorrected 20/20 vision) at least up 100 yards and I don't think you'd want to take a shot at a deer size animal beyond that distance. I had thought using the holosight on my own 1894C with the holosight near the front of the receiver. I decided on a Williams aperture sight as more appropriate to the gun (IMO) The magnification and sight picture is about the same as the holosight circle and dot. I wound up with a
Williams FP-336-TK using the two rearmost tapped scope holes on the top of the receiver (no side holes on my receiver). The Williams info on the sight says a hammer extension is required. I didn't find that to be so.
Here's a view of the sight picture with a 50 yard berm in the mid ground and just a tad of a 100 yard berm in the background. Both rifles would consistently hit clays and even pieces of clays at either distance. The holosights are quick to use, both eyes open, your eye does not have to line up with the sight axis. Whatever that little dot is sighted on is where the bullet will hit within the point blank range you're sighted in for. With the scope, you lose some of the quick acquisition of the holosight by itself.
