JP Enterprises 1-Piece Scope Mount is extremely robust and returns precisely to zero if removed and replaced. It offers the most ideal compromise between height and forward offset to be used on typical low rail flattop receivers with Mil-std 1913 Picatinny rail systems with longer eye relief high end scopes such as the Leupold LRT series. The profile is also an exact match to the CTR-02 upper receiver for an added touch. A torx key provided to tighten clamp screws. Manufactured to accommodate any 30mm scopes and includes a set of ring adapters so that it can be used with 1" scopes. Height (From top of rail to centerline of rings): 1.47"Includes: 5-countersunk flat-head screws on clamp piece 4- 6-32 cap screws on each ring strap (Torx keys included)
