Why the Repeat Zero Guarantee?

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 ratchet knobs, which only secure the 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, and once the laser/optic has been zeroed to a quality standard mil-spec dimensioned dovetail rail which is secured to the same weapon.
Easy on and off, no tools required, once the ring caps are secured: The spring loaded feature also acts like a shock absorber which provides a shock reducing barrier to sensitive optical/laser devices for extended service life and cost savings.
All A.R.M.S.® Throw Lever® mounts are designed to fit certified Mil-Std. 1913 Rails, via pre-measured spring loaded tension.  If one of our Throw Lever® mounts is too loose or too tight, the chances are you have an after market rail that is not dimensioned to the Mil-Std. dimensions.
 An alternative to attaching to after market non-mil-spec rails is to use our line of self-locking thumbnut mounts.
