A.R.M.S. #40L- SP FLIP UP REAR SIGHT SAME - PLANE DUAL APERTURE

The #40™L SP is identical to the #40™L but it utilizes our same plane aperture system. This aperture set allows the operator to choose between large and small apertures without worrying about them being zeroed to different ranges.

The Small aperture can also be removed if the user desires the larger CQB aperture only.
