The spring loaded cammed lever pulls in a downward force when the lever is pushed inward which does not disturb the windage (azimuth) normally encountered with thumbnuts, bolts, wrenches, and/or retchet knobs, which only secure with cross force direction and varying non-repeat tension. Because the Throw Levers pull down instead of across, it means positive controlled attachment not found on any other system. No threads to strip, no cross threading, ratchet wear, over-tightening, crushed or dented rails when using the A.R.M.S. spring loaded attachment. A.R.M.S. Throw Levers will also not freeze or absorb sand and mud like threaded and ratchet designs.

The unique force of direction and constant repeat tensions guarantee on and off repeatability. The rings snap into the same locked zero aiming position securely, each and every time, once the optic/laser has been zeroed to a quality standard mil-spec dimensioned dovetail rail, which is secured to the same weapon.
