ARMS Polymer Folding Front and Rear Sight Set AR15 BUIS
The new A.R.M.S. ® #71L series of spring actuated back up iron sights BUIS. These Front and Rear Sights with STEEL APERTURES, are not subject to distortion like thin plastic types. They are designed to allow attachment to all Universal Dovetail, Picatinny and Weaver style Rails. Both are made from durable, metal-reinforced polymer and are a good option when seeking a quality sight. Both are .600" when in the folded position, from the top of the receiver. Not for Dovetail Gas Blocks.
The #71L-F is rail mounted with a quick deploy latch and adjustable for elevation while the #71L-R features the same steel dual apertures, utilized in the A.R.M.S.® #40L® under contract with Crane Naval Special Warfare Center, for both CQB and long range shooting applications.
