I have one but I'm not sure if I want to use it on a bulgarian 74 or not. Anyone know what value this might have? It has the stock, grip, and both handguards. Most of the silver proof marks are easily visable, but some are kind of worn off. It's used but no major scratches and it has the buttplate and the metal (heat shield?) peice in the lower HG. Just looking for some guesses.
