I have one and love it. I picked it up on a customer return sale for about 25.00. I have used it on my TCR 87 in 22-250 and now have it mounted on a encore pistol, 15 inch barrel 22 Hornet. I think it will have enough eye relief with the light cal. to not cut my eye but I can push it out a little and not use the full field of vision but would not try this on a heavy kicker

one thing I can tell you is that if you do not lube the threads on the sun sheild or the screw on lense covers you are not getting them off. This was the reason for the return but I was able to remove the stuck lense cover, thing sure is long with the sun sheild mounted
