How is the height of the ring determined, and how much does this item cost in USD?
Dear Mr. Blake,
thank you for reaching out to us.
The BH is measured from the mounting surface of the rifle to the lower surface of the riflescope’s tube.
Please take a look at our blog for more information: https://www.optics-trade.eu/blog/scope-mounts-bh-height-and-kr-extension/
Unfortunately, due to the manufacturer’s restriction policy, we are unable to ship INNOmount products to the USA and CAD.
We apologize for any inconvenience this may cause and understand that this may be disappointing.
If you have any further questions or concerns please don’t hesitate to contact us and we will do our best to assist you.
