Product Description
Once an Rhop patch has been cut to length & fits inside a barrel's hop window insert it into this device. Run it over sand paper untill the patch is shallow enough that it barely touches a bb passing through the barrel. Once this is complete your Rhop patch is ready for its OD to be sanded to match the barrel.
