My stainless/synthetic 10/22 is currently slingless,a condition I`d like to rectify. The forend appears to be solid so a screw in swivel should work fine. However the buttstock I think may be hollow and I have my doubts as to if a normal screw in swivel will hold up under extended use without getting loose or rocking. Anybody here done one? What do you guys think,different type of mount maybe? Marcus
