Sling swivel stud


A sling swivel stud, sometimes called an "Uncle Mike type swivel", is a type of mounting point used for attaching slings and bipods to rifles.

Mounting a stud to a firearm

Sling swivels can be mounted to a long gun in various ways, for instance with wood or machine screws attached to the stock, a barrel band, or by using adapters to other mounting standards such as Picatinny or M-LOK.

Stud dimensions

The widest round part of the stud typically measures around 8.9 mm, the spacing between the flats measure around 7.6 mm and the hole for mounting a sling adapter measures around 3.7 mm.
