Samson A.R.M.S. #40L Flip Up Rear Sight (Low) and #40L-SP Plane Dual Aperture Product Info

Samson A.R.M.S. Stand Alone Flip-up sight is Samson shooting accessory that 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 of the ARMS #40L Flip up Rear Sight by Samson 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 of this shooting accessory utilizes the standard M16/M4 front sight bead. When the sight is released into battery the 250-300 meter aperture is ready for immediate close combat use. For longer ranges the leaf sight aperture is rotated to access the 500-600capability with the built in horizon line feature that helps lead distant targets and lets the shooter square the rifle to counter windage offsets, if the rifle is inadvertently tilted. Other type rear iron fold-down sights require the shooter to push it into position, which means they can be accidentally knocked down at the worst time. The Samson A.R.M.S. spring loaded flip-up sights never let you down, because those Samson shooting accessories are designed to always be there even when going thru brush or being dropped. The Samson #40L SP is identical to the Samson #40L 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 of ARMS 40L SP by Samson manufactory can also be removed if the user desires the larger CQB aperture only.

Great back-up sight for my AR rifle. I typically use an EOTech holographic sight on my rifle, but this is a great back-up sight as it folds down out of the way when not needed. But is quickly accessible and holds zero when you need it. Pros: Folds d...
