16" Wilson Combat Ranger Stainless Steel barrel. Barrel is new in the packaging. Has never been used or even test fitted to an upper. Barrel will fit most DPMS style 308 AR type upper receivers such as Aero Precision M5. It is buyer's responsibility to determine if the barrel will work for them. Barrel Sold as is, no returns or exchanges. I purchased the barrel for a project and never used it. Barrel has been in storage in the plastic tube it was shipped in. Happy to answer relevant questions. Buyer pays shipping on top of cost of barrel listed. Willing to negotiate price a bit.
