If you had a chance to by a MAK 91 (NHM 91) what would be a good price. Has thumb hole stock, long barrel, 30 round clip, missing muzzle brake barrel (is threaded for one,) the pin that holds it in place has been cut off. Ser # begins with 93 (yr?). Few nicks and scratches but no bad, barrel rifling's look good. What do you think,,,, any info would be greatly appreciated..
