This mount comes standard with a bevel on both sides making it ambidextrous.

The bolt pattern on our Remington 700 Short Action mount fits Short Action Remington 700 rifles (example 223, 308), as well as the 722 and 40x. Despite what you may have heard, the Remington 700 mount will NOT fit your Howa 1500 or Weatherby Vanguard. The bolt pattern is similar, but the remainder of the mount (ejection port, length, etc.) renders it useless on these two guns.

The middle spread is the distance between the two middle holes, center to center, on your receiver.
