Looking to trade a Sig 556. I have installed the Sig Diopter Sight ($133) and the Commando 552 forward hand guard ($90). Gun is like new, with about 100 rounds fired. Cash price is $1300. I am located in the Hillsboro/PDX area. I can remove the Diopter site and sell the gun for $1200. I will include the original picatinny rail hand guard with gun as well. Sig Gun case included. Things I will consider taking in on trade/partial trade: Aimpoint Pro Aimpoint Comp ML3 (2 moa) w/LaRue Mount Aimpoint 3X magnifier w/twist mount .308 ammo (FMJ, no soft point or hunting ammo) Honda EU2000i Inverter/Generator Please PM me for pictures or if you have any questions.
