The Athlon Talos BTR 1-4x24 scopes have removable locking screws of windage and elevation turret knob. Once a rifle has been sighted in, simply remove the screw and take out the turret knob. Put the turret knob back on with zero line aligned with the vertical mark below the turning knob, then tighten the screw to lock it in.
To mount the Athlon Optics 1-4 x 24 mm Rifle Scope to an AR I recommend using a cantilever mount like the one at the link below.

I recommend using the Butler Creek Flip Open Scope Covers for the Athlon Optics 1-4 x 24 mm Rifle Scope. You will need the Butler Creek Flip Open Scope Cover size 2 for the objective lens and size 20 for the eyepiece. These two covers can be found at the link below. The Athlon Optics 1-4 x 24 mm Rifle Scope has a low profile throw lever on the magnification ring, so an aftermarket throw lever may not fit properly. However, the throw lever at the second link below will fit the diameter of the magnification ring on this scope.

This scope does not come with rings or a mount.
I would recommend the Vortex Defender caps, MPN: O-24 and MPN: E-10 found here:
