Helpful Positive Review MORE THAN BACK-UP by Legacy Reviewer, Verified Owner, August 6, 2011

This is a go to sight often relegated to the role of a back-up, as it is built to fit nicely under most proper eye position mounted primary optics. My kids and I use it as a primary sight on our non-precision rifles. Pros: Intelligent Design and Har...

Most Recent Reviews Great flip up rear sight by Legacy Reviewer, Verified Owner, March 26, 2012

Every thing I was looking for in a flip rear sight. Took me a second to figure out install since you have to slide it along rail to install.

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

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