Barrel and Receiver Screw Sizes

[XenaRB]

So I’m trying to find the two barrel and two reciever screws for my Ruger Carbine. Are there any sources for these?

if you are talking about the "plug" screws ,just call the factory ,customer service ,,,we use 'capped' plug screws to "fill in the empty holes, looks neater, more "finished".
