Lever is obtained as which is the mechanical advantage of the lever. This equation shows that if the distance "a" from the fulcrum to the point "A" where the input force is applied is greater than the distance "b" from fulcrum to the point "B" where the output force is applied, then the lever amplifies the input force. If the opposite is true that the distance from the fulcrum to the input point "A" is less than from the fulcrum to the output point "B", then the lever reduces the magnitude of the input force.

Colt Ring Lever rifles a year after acquiring fifty First Model rifles, Colonel Harney remarked that all but two were in good working order. Later in July 1839, however, a surprise Seminole attack led to the loss of thirty Ring Lever rifles, though fourteen were eventually recovered. In spite of the rifle's reliability problems, support for Colt's rifles was garnered from field officers, especially from Lieutenant Colonel Harney. Harney commented on Colt's Ring Lever rifle favorably, stating: "I honestly believe that, but for these arms, the Indians would now be luxuriating in the Everglades of Florida." Colt capitalized on Harney's testimony to produce a
