Looking to sell 2nd gen (good one) sig556r 7.62x39. Has free float troy rail, collapsible magpul moe stock(folding) 5mags. Flip up troy irons. Previous owner dura coated. Not sure on round count. I've put 100 through it flawlessly. The only issue I have with it due to the troy rail is the weight. Put a stock Swiss handguard would drop it back to 7.5lbs. 1,200 obo or trade for battle rifle. Thanks.
