I have upgraded and changed colors so need to sell this one. This is a Tactical Solutions .920, Ultra Light Weight barrel for a Ruger 10-22. It is 161/2", matte black, fluted, and is not threaded. My best guess would be around 200 rounds fired through this one. http://www.tacticalsol.com/index.ph...e.tpl&Itemid=62&category_id=22&product_id=121 Looking to sell for $155 FTF or $165 shipped. Delivery along I-5 to Seattle possible this week.
