Evolution Gun Works HD Picatinny Scope Mount Rem XP 100 7 4-Hole 20 MOA. Picatinny cross slots run the full length of the Evolution Gun Works Scope Mount which gives the shooter flexibility when mounting scope rings and other accessories. The cross slots are also machined the full width of the mount and gauged to MIL-STD 1913 specs maintaining tolerances of +/-.002". The EGW Remington XP100 Rail is lower in height than other tactical rails which reduces weight and gives the shooter a better cheek weld.
