Recoil is quite stout w/ 12ga slugs, 3.5"+eye relief and sturdy construction is critical. steel rings are a good idea too. Id shop around for a good deal on a candeliver mount slug barrel alone, and buy a bushnell trophy(about 90$) separate , I know for a fact that scope will hold up, and ER is adaquate. Thats is the cheapest, cheap scope I would get for a 12ga.
