I appreciate your recommendation Vitamink. Matter of fact my Saiga 12 is a Fist of War conversion by TAC 47. I bought it locally from an aquaintance.
Thanks to Cameron's generous offer I am going to order 2 CHAOS rails within the next week for 2 new Saiga 12 conversions I have in mind (including a 12 inch SBS). In this case wanted to see if there is a cheap charlie method of adding a red dot sight to my shotgun.
