Precision machined to true MIL-STD 1913 specs, this base rail will accept both Weaver and Picatinny rings for a variety of sight options. Streamlined, shallow profile is low enough to allow the use of iron sights while installed, however optics may have to be removed. Fits Weaver-style and Picatinny receiver rails.
