I saw a 11-87 SPS Super Mag for sale with a monte carlo raised rear stock. I never saw this type of stock on one of these before and was wondering if this was original from the factory or if this was most likely added later? I have 2 11-87's and they both have the straight rear stock. I added photos of both the monte carlo and straight stock below. What would be the difference and what advantage would the monte carlo stock have over the straight? It's on a 11-87 SPS Super Mag Camo with a 23" vent ribed turkey barrel. I just want to make sure the entire gun is complete original as it shipped from the factory before I think about making an offer on it. Thanks for any info!!
