Leupold Cross-Slot mounting systems feature Quick Release Weaver-style rings that work with both Weaver or Picatinny rails with 1-piece and 2-piece bases available for many popular rifles. This QRW (Quick Release Weaver) model is designed to fit a Tikka T3/T3x and is ideal for standard to magnum calibers. QRW2s also work with cross-slot bases and offers the same features as our QR mounts, including +/- 1/4 MOA accuracy when removing and replacing your optic.
