I'm working on a folder for my saiga using the left over Vepr 12 laminate stocks. Refinishing is almost competed (attempting a plum rit dye). Now for the meat and potatoes- I need a sling swivel for this stock, but k-var and similar sites rarely list dimensions for the rear sling swivel bases. The Vepr stock is milled out for a 1/2" wide base x 1 7/16" base. Does anyone know which country of origin produces a base in those dimensions? Any information would be greatly appreciated. Information with links would be even better. Thanks in advance and a quick preview. Edit: A quick addition; m
