Quality, Rugged, Match Grade Upper Unit

Fully machined from aircraft grade aluminum alloy, with extra material around the bolt carrier to provide a strong, rigid, platform for mounting heavy match barrels. Integral Picatinny-style scope rail gives complete flexibility for mounting all types of sight systems. Accepts Weaver-style rings. Eliminates the forward assist and ejection port cover for easier operation and smoother profile. High Rider - 1" high rail height is correct for scope mounting with low rings. No need for a cheek pad; permits large objective scopes to clear the hand guards. Lo-Pro - Standard height rail allows use of detachable carry handles. Convenient mounting for electronic dot sights.
