The Picatinny rail designs give you more options to mount your scope and accessories without requiring gunsmithing or permanent alterations. The Single Rail (SR) style reduces weight and is composed of tough, extruded aluminum. This rail attaches securely with easy-to-turn, steel thumbscrews that have threaded steel studs. You can use both Picatinny or Weaver-style accessories and rings with this rail, and it comes with mounting recesses and screws for STANAG rings. The carry handle version has a sight tunnel that allows you to use the adjustable A2 factory sights without obstruction. The flat top version raises the line of sight by .870" to give you improved eye relief and a more comfortable cheek weld when using conventional or electronic optics. You can choose between the A2 carry handle or A4 flattop receivers, and both models attach quickly with either single or dual thumbscrews.
