The BKL 260HMB one-piece mount is a heavy-duty solution for shooters who want maximum clamping strength and perfect alignment on 11mm dovetail rails.
Built as a unitised 4" long mount, it uses six clamping screws across the base to distribute pressure evenly along the rail. This gives a far more secure hold than standard two-piece rings, especially on air rifles and rimfire setups with recoil or vibration.
BKL’s self-centring clamping system pulls both sides of the mount together evenly as it tightens, keeping the scope aligned with the bore and reducing stress on the tube.
This high version provides increased clearance, making it suitable for larger objective lenses and rifles where extra height is required.
Profile - High - 37mm base to ring center. Equates to maximujm scope "OUTER" objective case diameter 72mm - so any big scope works. Example, Hawke 50mm AO scope will have 8mm clearance on a totally flat base.
Best suited for:
- Air rifles with hefty recoil (spring/gas ram)
- Rimfire rifles (.22LR etc.)
- Scopes with larger objective lenses (up to ~56mm)
- Setups needing maximum clamp security
