EGW recommends measuring the hole spacing in your receiver to confirm it matches with the dimensions they have published. Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. EGW one-piece scope mounts are the obvious choice for hunters and tactical shooters alike. This mount is a Picatinny-style base and compatible with Picatinny or Weaver scope rings. EGW machines these in their shop using one of their machining centers. After machining, the mounts are tumbled, sand blasted, and Type III anodized for long lasting durability. Recommend: 20 MOA - if shooting 500-1000 yards Mfg: Egw
