What say you? edit: Pretty sure I've made up my mind....
A fellow suspected it is an RS, but, it's definitely different than my RS. Note, hollows around the front takedown, and definite injected-poly-like grip cap.
Early 90s poly? Shirley (lol) in hand, poly or not, is not a difficult choice... Hmmm.
My RS. Modified but I don't recall there being a "grip cap" like an injection molded poly stock. Forearm Inletting is definitely different. IIRC, mine was solid for a couple few inches ahead of the recoil lug, unlike shown above.
