Just ordered the 1.65 - 5X36 for a CVA Accura 2. Decided on that scope after looking at an old Burris 1.5-5X20 and realizing that it was more than adequate for the weapon (except for the fact that the dearler was asking a bit too much for a discontinued, several year old scope). The important part is that both of the scopes you are evaluating have 5" of eye relief. I am not an expert on the topic, however, I have been nailed between the eyes 2 times (makes me sad that 1 time was not enough). And just by happen chance I just saw a kid end up with a goose egg between his eyes yesterday; produced by his wolf with a low eye relief scope. Burris makes a 2-7X35 and Leupold makes a 2-7x33mm. Both looked like good options. But I wanted the lower power for tight quarters. I will be sighting in the scope next weekend (if I can figure out why tripple 7 is jacking up my weapon so bad).
