The Warne Shotgun Rib Red Dot Mount (6108M) is a steel clamp that fits a red dot sight or a short Picatinny rail section to a shotgun's ventilated rib without drilling, tapping or any gunsmithing. It grips the rib itself, so the gun goes back to standard the moment you take it off. Covered by the Warne Lifetime Warranty.
How It Compares
Unlike a receiver-drilled base, this mount is completely reversible and needs no work on the gun. Browse the shotgun red dot sights that fit it, the full Warne scope mount and ring range, or every optic mount we stock.
Ideal For
- Adding a red dot to a vent-rib shotgun without drilling or gunsmithing
- Practice and clay shooting where a dot helps confirm where the gun is pointing
- Vermin and pest control with a shotgun, where a dot is quicker to pick up than a bead
- Anyone who wants the option removed again with no permanent change to the gun

Frequently Asked Questions
Do I need to drill my shotgun to fit the Warne 6108M rib mount?
No. The Warne 6108M clamps directly onto the ventilated rib, so no drilling, tapping or gunsmithing is required and the shotgun is unmodified when the mount comes off.
Will the Warne 6108M fit my shotgun?
It is made for common ventilated-rib widths. Measure the width of your rib and check it against the fitment range before ordering, or send us the measurement and we will confirm.
What can I mount on the Warne 6108M?
A compact red dot or reflex sight, or a short Picatinny rail section that a red dot then attaches to.
Does the Warne 6108M work on a shotgun without a ventilated rib?
No. It is a rib clamp, so it needs a ventilated rib to grip. A shotgun with a solid or flat rib, or no rib at all, needs a different mounting method.
