i'm going to sell my SIG 556 scm. it's chambered in 5.56. it's a long stroke piston driven rifle. it comes with one 30 round mag and does take standard ar15 mags. its in great shape. very low round count. i just dont shoot it. great gun though. would be a great suppressor host being piston driven. feel free to pm me with any questions. $1100shipped to the lower 48
