A.R.M.S. #40 - BUIS 200-600 Meter


The standard ARMS #40 rear back up iron sight is equipped with both 250-300 meter and 500-600 meter aperatures. The 500-600 meter aperture includes a built in horizon line that helps lead distant targets and lets the shooter square the rifle to counter windage offsets if the rifle is inadvertently tilted. When engaged, the sight springs up to allow immediate use of the larger close combat aperture.

A.R.M.S. #40A2 - BUIS 200-300 Meter


A.R.M.S. #40A STAND ALONE FLIP UP REAR SIGHT 250-300 METERS - The A.R.M.S.® Stand Alone Flip-up sight, utilizes the same well proven concept as the rear sight on the SWAN® Sleeve system. The unique design of the spring loaded rear sight, ensures constant battery action and repeat zero. The sight is held in the locked down position by a quick release lever, that prevents the sight from being accidentally engaged, but is as fast as a trigger to release even with arctic mittens. The initial elevation zero utilizes the standard M16/M4 front sight bead.

A.R.M.S. #40L - Low Profile BUIS


The ARMS #40L has all the features of our excellent #40A2 series sights but has a lower profile, allowing more clearance for mounting optics on the flat top receiver.

A.R.M.S. #40L-SP - Low Profile BUIS - Same Plane


The ARMS #40L-SP is identical to the standard low profile rear sight but utilizes a same-plane aperture system that allows the operator to choose between aperture sizes without worrying about them being zeroed to different ranges.  The smaller aperture can be completely removed from the sight if the user wishes to use the large CQB aperture alone.

A.R.M.S. #40 Low Precision


The P stands for precision .50 MOA, = minute of angle means at 100 meters, each click of the windage knob moves the point of impact .50 left or right. The sight also has new notches above the round apertures for faster CQB engagements inside of 50 meters and also for long range 500-600 meter. New improved feature is the captivated nut.
