  • Information
The Williams QC side mount has been a favorite of big game hunters for years. Why a side mount? With a side mount you have the top of the receiver clear of bases. This allows a receiver sight to be in place and usable at the same time. Also, on a bolt action it offers more unobstructed area for loading the magazine, so important with the today's large diameter magnum cases. The special cam-lock thumb wheels allow the scope to be removed and replaced instantly with absolute return to zero. Permits the shooter to have both scope and iron sights always available for instant use. HCO series rings mount the scope over the center of the bore. They may also be rotated 180 degrees to offset the scope to the left of the rifle for the shooter who shoots from the right shoulder but must use the left eye. Split series rings are typically used on top-eject lever actions as they locate the scope directly above the center line of QC side mount base. Special high HCO and Spit rings are .200 taller to accomodate scopes with large diameter objective bells.

Technical Information

  • QC side mounts permit the shooter to have both scope and iron sight available.
  • Mount is purchased for a particular firearm model, and then QC rings are used to mount the scope directly over the firearm's bore or offset.
  • If mount is used with regular or split QC rings, scope will be offset from bore and iron sights
  • If mount is used with HCO (High Central Overbore) rings, scope will be positioned directly over the top of the rifle's iron sights.
