Flash suppressor has been unpinned and barrel threaded to accept a can. Machine work was done at Sig Sauer. 50 rounds were put through it afterwards. I bought the rifle at the end of last year. Ive been traveling and havent had a chance to put any rounds down range, unfortunately. I found a project Im interested in more than I need this rifle at the moment. $3200 for everything. I respond quickly to texts. Im not interested in trades.
