A.R.M.S.® #40™ Stand Alone Flip Up Rear Sight .75 MOA.
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 in 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. Has military horizon line notch, 500-600 meter sight. Windage adjustments .75 MOA
