I should clarify, are the Ambi stocks interchangeable? The reason I asked is that the LH and RH are listed for both models but the Ambi stocks are not.
Oh sorry, yes it will. If a RH stock will fit both guns and an ambi will fit the s510 then it must fit the 410 as well right? When I had an s400 I was going to buy an poplar ambi stock from PA for it, just ended up trading it before I did.
