DSA ARMS This is a new build in 5.56/.223 it has only been test fired for function. Has quad rail and alluminum parts have been anodized Blue. It has a stainless barrel with an 8 twist. Gun looks really cool just not my cup of tea I took it on trade for a rifle I was asking $1800 for. I want $1899 or I will just keep it and see what happens with the laws.
