This a very limited edition Sig 556 Commando. It has the Swiss 551 dark green hand guards which look much like the Classic's,and has a dark green Magpul CTR folding/collasping stock. The Grips are also dark green and I will include a dark green Magpul 30 rd mag.
This is a new in the box, never fired collectible gun with original bill of sale, and all papers that came with it.
IMO is is a far superior design than any AR though it does have the AR's accuracy with the reliability of the AK47 system since it is basically an improved AK system. It has very few parts as compared to the AR and they are all VERY robust and strong.
Price is $2300. No trades wanted
