FAQ

What is the purpose of the 20 MOA slope on the BackCountry Cross-Slot One-Piece Base?

The 20 MOA slope is designed to extend the elevation adjustment range of your scope, which is particularly beneficial for long-range shooting scenarios. It allows for more precise targeting at greater distances.

Can the BackCountry Cross-Slot One-Piece Base be used with any scope rings?

While it is optimized for use with Leupold BackCountry Cross-Slot Rings or Mark 4 Aluminum rings, the base is compatible with any rings that fit Picatinny rails, offering versatility in your choice of mounting hardware.

Is the BackCountry Cross-Slot One-Piece Base difficult to install on a Ruger American Long-Action Rifle?

The base is designed for easy installation, allowing shooters to securely attach it to their Ruger American Long-Action Rifle without professional assistance, provided they follow the proper installation guidelines.

Will the addition of the BackCountry Cross-Slot One-Piece Base affect the balance of my rifle?

No, the base is made from lightweight 7075-T6 aluminum which ensures minimal impact on the balance and handling of your rifle while providing a strong and stable platform for your optics.

How does the matte black finish benefit the BackCountry Cross-Slot One-Piece Base?

The matte black finish not only adds a layer of protection against corrosion and wear but also reduces glare and reflection, ensuring that it does not distract or give away the shooter's position in the field.
