jackspackThis is an OE SIG .556 5” barrel. I put maybe 100 rounds thorough jt. I had the factory flash hider professionally removed and installed a HUXWorks flow flash hider installed for my can. Never even shot it. I went back to my .300BO set up. These are $699 and up brand new. You can put a different flash hider on it or the OE which is included. Shipped to you for $400. Trades considered. Try me
