Harris No. 2A bipod adaptor

Swivel Stud Adapter for Rifles Without Factory-Installed Studs

Perfect for rifles like the Ruger M77 RP MK2 and other carbines that lack a front swivel stud in the stock.

5/8" diameter round flange

Made in the USA

Durable and secure fit

This adapter is designed for firearms that do not come with a pre-installed swivel stud. The round flange provides extra grip and stability when installing the swivel stud into the stock, ensuring a solid connection point for your bipod.

Important: You'll need to drill a hole into your stock at the desired location. Make sure it is perfectly centered — an off-center hole will cause your bipod to sit unevenly.

Compatible with Harris and Harris-style bipods, this adapter allows for a secure and reliable bipod mounting solution on rifles that otherwise couldn’t support one.
