Hello VarmintGuy and thanks for the welcome.
That is a Leupold rifle scope sitting on top, with 3 1/2" eye relief. Move your head close to get on target, then back up just a little bit before taking the shot. With the weight of the gun and the added on muzzle brake, recoil is comparable to that of a 22 Hornet or less, depending on load and bullet weight.
Accuracy wise, 3/8" @ 200 yds. on a bad day.
