The A.R.M.S. #19 ACOG Dual Throw Lever Mount for ACOG scopes features most of the design of the #19A, with the addition of the ACOG channel. This mount provides the ACOG scope three positions of added relief to select from.

The #19S ACOG is a compact single Throw Lever base that is the same length as the built in M16 carry handle mounting platform (approx. 4") found on all ACOG scopes.

Required for proper co-witnessing with iron sights when using 22M68 throw lever mount directly on a flat top receiver.
