For use on all A.R.M.S.® #21, #22, and #35 Ring saddles. Shown with #22TRR (Front ring) and #22TRS (Rear ring) attached. This unique ring cap was designed to expand the standard use of a cap normally only holding a scope in position, to that of allowing modular enhancements on various conventional optics by simply removing the standard cap and installing the tactical cap using the same socket head screws.
