Push button QD swivels

If you mount hese on the side of a bolt gun make sure you put them on the opposite side of the bolt handle

Yes, Military guns used to have sling swivels mounted on the front of the trigger guard (a third point) but this has pretty much gone away along with the concept of marksmanship...

no not the old 3rd point in front of the mag for a 3point sling like on the old No4


a Single point is a modern thing
