Not Polytech! This has a dull finished chrome follower and only 1 witness hole on the flat back. No China on bottom plate. Blued Finish and overall condition is excellent except for a very small spot of surface rust [size of rice grain] $24 shipped where legal. First I'll take it followed by an IM or email gets the mag. USPS money or Paypa [F&F or add 3%] Pics will be up asap. Thanks for looking!
