It's one way Leupold does it.

 

It sounds like marketing terminology not standard terminology.

The print is too small for me to read and analyze.

 

Is this better ? You need glasses ! :-D :lol: If your Leupold Tactical Riflescope is a model with M5A2 Auto-locking
Push Button adjustments, you must
depress the button in the center of the
adjustment dial to release the lock while
turning the dial to make the adjustment.
The adjustment dial will automatically
lock into place at any point within the
dial travel when the button is released.
If your Leupold Tactical riflescope is a model
with M5B2 Auto-locking Pinch and Turn adjustments, you must pinch the lock release
ring around the dial to release the lock,
while turning the dial to make the adjustment. The adjustment dial will automatically lock into place at any point within the
dial travel when the lock ring is released.
If your Leupold Tactical riflescope is a model with M6C1 Zerolock™
adjustment dials, you must push inward on the lock release button
located on the outer edge of the dial above the zero indicator mark

to make an adjustment. Once the dial has been turned one or more
clicks past the zero position it is no longer necessary to press the lock
release button. The Zerolock adjustment
dials will only lock when at the zero
position of the dial travel.
Many of the adjustments on Leupold
Tactical riflescopes are equipped with a
rotational stop, zero stop, or hard stop at
both ends of the dial travel.
Some Leupold Tactical riflescope adjustments also include a revolution
indicator to keep track of dial position through more than one
complete revolution. Please see pages
20-22 for information on re-setting the dial
revolution indicator.

its still too small to read, lol

 

There goes the band width on the forum for the next 2 years. Now we really won't be able to post pictures. :th_roll:

 

i am guessing the M5A2 is some military specification for their enhanced sniper rifle scope (locking turrets).

this is the option that you want to uncheck.
this makes thumbnals i cannot see that open up to the same stupidly small picture. i don't think it works the way it is meant to.
