Quality, Rugged, Match Grade Upper Unit

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.
