Leupold Cross-Slot mounting systems feature Weaver-style rings that work with both Weaver or Picatinny rails with 1-piece and 2-piece bases available for many popular rifles. This model is designed to fit any riflescope with 1" maintube and is ideal for standard to magnum calibers. Leupold's Cross-Slot mounts include the PRW2 QRW2 LRW and Open Range series and deliver unmatched durability and strength. The PRW2 mounts are very popular since many rifles come with Weaver-style bases or cross-slot rails. QRW2s also work with cross-slot bases and offers the same features as our QR mounts including +/- ¼ MOA accuracy when removing and replacing your optic. The LRW series mounts quickly and easily and offers a traditional look while the Open Range series is made from lightweight 6061-T6 aluminum–both are compatible with cross-slot bases. Nothing is more crucial than the link between your scope and firearm. That’s why these mounts are every bit as rugged and dependable as the Leupold optics they secure. And with a huge variety of mounting systems to pick from you're sure to find the perfect match for your firearm and style of shooting. Made in the USA and guaranteed to hold up to a lifetime of abuse Leupold mounts will never let you down.
