Ask a Question
  • Will this rail work with mdt or 419 bipod clamps

    You mean like this?  If so, yes.  This arca rail will work with any bipod clamps meant for an arca rail.

  • What exactly is R-lock and does it require a special bipod arca clamp or will an area 419 clamp work

    Its just a pin that some clamps are now using that helps lock the rail into place.

  • How much torque do you recommend for these screws?

    We don't have a torque spec, just snug and a 1/4 turn past that.

Greyboe Ridgeback Arca Rail

Fits looks great and fits perfectly. Very easy to mount. Extends nicely past fore end. Really like how it uses the recessed M-Lok slots to mount.

Awesome product!

I had an Arca rail attached to my ridgeback stock but it was a modified m lok one and didn’t go back towards the mag well far enough. This one is perfect! Great fit and is going to do everything I want it to do

Purchased for 16lb 32" barreled 300 RUM. This thing is rock solid. It is fit perfectly to cutouts for the mlok rails rather than attaching to then. Goes around front action screw so can stay mounted 100% of the time. This will support and rig you put it on. Also it lets me run my bipod about 2-3" forward of where i could using mlok slots. This really helps balance weight of long heavy barrel.
