bushnell ar optics?

[6.5x55swm]

i was thinking of getting one these for my 223 for coyote hunting and it has exposed turrets, do they lock in place? looks like it would move pretty easy while hunting if they don't lock

They don’t lock but are fairly stiff to turn
They also can be reset to zero so if they do move you can set it back to where it was
