Weaver
The Weaver Single Rail Scope Base for AR-15 flat-top receivers is a straightforward, lightweight solution for mounting optics and accessories on your modern tactical or hunting rifle. Built from extruded aluminum and finished in matte black, this Picatinny-style rail base bolts directly to your flat-top upper with steel thumbscrews—no gunsmithing, no permanent drilling. It raises your line of sight by 0.870 inches, giving you the eye relief and cheek weld comfort you need whether you're running a conventional rifle scope or a red dot sight.
This single-rail design keeps unnecessary weight off your gun while maintaining full compatibility with both Picatinny and Weaver-style rings and accessories. The base arrives ready to go with mounting recesses and screws pre-drilled for STANAG-pattern rings, so you can have your scope secured and zeroed in minimal time. The streamlined profile won't interfere with your charging handle or rear sight if you keep irons as backup, and the matte black finish blends seamlessly with most AR builds.
Whether you're setting up a precision rifle, a hunting AR, or a duty gun, this Weaver base is the kind of no-frills, dependable hardware that lets your optic do the work. It's not flashy, but that's the point—solid engineering, smart engineering, the kind of mount that disappears after you bolt it on.
