I wouldn't say that one is more proper than the other, both will perform. Once the scope is mounted with either setup there's no fiddling around needed, so I don't think either will help you get a good shot. That part is up to you. [8D]

The optilock rings have the plastic insert to hold your scope so you don't need the extra step of lapping the rings. That keeps you from putting stress on the scope tube. They line up very nicely, so the alignment rods aren't needed. That's another step off the installation process. The lower half of the optilock ring is screwed into the base from below and then the base slides into the rail already lined up.

My Sako and Tikka installs of new scopes on new rifles required no adjustments to windage and elevation using my Leupold boresighter. Very little was needed at the range as well. That's a testament to the rifle as well as the scope mounting. My Browning on the other hand, with it's Leupold bases and rings, reqired a trip to the range, some shims, the purchase of alignment rods and lapping kit, and another trip to the range. Now that I know better and have the alignment kit, the first trip to the range wouldn't be needed. But for me at the time it was an extra expense.

Leupold makes good rings and bases. They will serve you well. My needing shims was a bummer, but it happens. Must happen somewhat often as Leupold has 'em in stock and sends 'em right out to you. So its not just me. Once they're on and you're sighted in it's over and done with. Both are solid enough for most rigs. I like the Optilocks enough that I would lean more towards a Sako/Tikka purchase over Browning/Winchester just so that I could get them.

Stubblejumper like the Leupolds, I like the Optilocks. I'd be interested in hearing other opinions too. You might try posting in the guns forum for more responses.
