10 in stock

The Rusan Steel Quick-Release Picatinny & Weaver Rings (40mm, Height 11mm) are precision-engineered mounts designed for secure, mid-height, and easily detachable installation of 40mm scopes on Picatinny or Weaver rails. Crafted from high-strength steel, these rings provide exceptional rigidity, recoil resistance, and repeatable zero retention. The 11mm height offers extra clearance for larger scopes or accessories while maintaining a comfortable cheek weld. The quick-release mechanism allows rapid attachment or removal of optics without tools, making these rings ideal for tactical setups, hunting rifles, and long-range precision shooting.

MOUNT SIZE GUIDE
Ring Height Calculator
This calculator works out the minimum ring height (base-to-centre) you should use, including a tolerance allowance.
Please note: All clearance calculations are based on mounts with 0 MOA. While MOA can be factored in, actual clearance may vary due to variables that can't always be accurately calculated. If you're considering an MOA mount and are unsure about the required height, we recommend contacting our sales team directly.

Diagram showing where to measure scope cover thickness

Measure the thickness of any scope cover if used. If none, leave as 0.

Diagram showing where to measure rail to barrel clearance

Measure from the top of the rail to the highest point of the barrel.

Tolerance
We add a little extra clearance to account for real-world variation. Default is +1 mm.
Minimum Ring Height Needed: 0.00 mm (0.00 inches)

Enter your measurements above to calculate the lowest ring height (base-to-centre) you can realistically use.
