Can anyone give me any info on this gun? I bought it from an estate auction. 15" barrel in .223. Supposedly this is the way it came from Remingtons "Custom Shop". I would be interested in a catalog from Remington or any other printed matter relating to this gun. Would like to know original selling price, if someone knows that info. What accessories were available and anything related to this type of gun from the custom shop. Thanks, Bulge.
