Need cash to fund new project. $500.00 Comes with 2 30rd mags. the muzzle device welded all the way round per ATF specs. 11.75 inch barrel with a 5.5 inch muzzle device welded on adds up to a 17 inch barrel leaving 1/4 inch for thread overlap. At least that is what Dan at the BATF office in Seattle said when I called and asked before I had this put together.
