Frequently Asked Questions
Will it fit my rifle?
It clamps tool-free to any Arca-Swiss rail or plate on your forend or chassis.
Does the quick-detach clamp hold zero?
Yes — the tool-free QD clamp is designed to install and remove in seconds while reliably retaining zero.
What is the difference between the WB-4 and WB-5?
The WB-5 uses longer legs for higher shooting positions, while the WB-4 is lower and more compact for prone work.
