Just got a Nikon Slughunter scope for mine, it has 5 inches. I use it with a Knoxx Spec-ops stock which moves toward you when you fire and it still has enough.
I use a Bushnell Banner 3X9 with 6" of eye relief on a H&R Ultra Slugger. I have no complaints and would recommend it to others.RMc said:Oops! No edit in this part of the forum.
Here are the specification.
