Fitment Notes

The recommend torque setting is 50 in-lbs. We would suggest starting at 45 in-lbs and see how you get on.

The floorplate is designed to reuse the action screws from the hinged floorplate.

Please note that some aftermarket stocks (e.g. GRS Berserk) have fixing holes wider than the holes on factory stocks, if you find this is the case we recommend fitting a thin washer to support the floorplate over the gap.
