First thanks to Two Rivers did who the build. Started out as an unfired 1987 Polish AKMS kit, probably should have looked for something earlier since the scope's log says it was zeroed in 79, but oh well. Two Rivers did the engraving on the rail to match the serno on the trunnion and NSP-3, the font and size look spot on. One of those new polish barrels and Childers receiver round it out. Two Rivers-You have any thing to add about using these NOS rails and repro strut arms?
