Installed the cantilever ring with my StrikeFire and VMX-3T magnifier. The red dot now has enough room for the BUIS without interference. The offset is exactly as described, and the fit is secure on the rail.
Harry Murray –
Works well with my current setup. The ring moves the red dot forward as expected and gives me better access to the rear iron sights. Slight adjustment needed for magnifier alignment, but overall a solid addition.
Caroline Roberts –
Perfect for users who need to combine red dot sights with magnifiers. The 1-inch offset is just right and doesn’t compromise the mounting stability. Easy to install and holds firmly.
