A.R.M.S. 40L Flip Up Rear Sight

The standard in folding sights, this is the improved low version of the classic A.R.M.S #40 sight. It is designed to clear most any optic on your tactical carbine. Still the best sight available for quick transition from electronics to irons. This sight is suitable for duty or combat use in virtually any environment. It is intended as a fail safe device.
