I have a Brand New MEC Steelmaster Reloader 12 Gauge 3" for sale. Opened box and looked inside, but never pulled it out. I bought this unit 2 yrs ago and never used it and have no plans on using it so my lose is your gain. Just pm me for a price if your interested. You can look up pricing on the web and I will be lower than what you find, just not going to take a huge lose from it.

I copied the technical and specification for it. Picture posted is a copied picture. Box and MEC model picture taken by me. If you want me to take it out of the box and take a picture I can do that if needed.
