GrovTec GTHM198 Push Button Sling Swivel Base for Hollow Stock - Full Rotation

The GrovTec GTHM198 Push Button Base is a full-rotation quick-detach sling swivel cup engineered specifically for installation on hollow or thin-walled rifle stocks that are not thick enough to support a traditional threaded base on their own.

Constructed from all steel with a durable black-oxide finish, this low-profile base uses a 9/16-18 mounting thread that passes through the stock wall and is secured on the inside by a mating panel nut, with a standard push button swivel cup on the outside that accepts any common quick-detach sling swivel.

The GTHM198 is a practical upgrade or replacement part for any rifle or shotgun whose stock geometry won't accept a standard threaded swivel stud, giving you a positive, repeatable QD mounting point for your sling and swivels on hollow tube stocks, thin synthetic stocks, and other limited-clearance designs.
