They are good for close range shots but if the bell on your scopes objective is hitting the receiver it will probably obscure the openings on the see thru mounts. I have see thru's on my 460 magnum but my leapers scope has a 50mm adjustable scope objective and I can barely see thru them. Don't forget that when you put a scope that high on your airgun that it changes the angle that your gun shoots and the farther out the bullet or pellet travels before it crosses the line of sight. On my gun it's 2inches from center of bore to the line of sight, and I have to aim almost 2 mils low at 10yrds or I miss the target.
