This is an Aero Precision AR10 chambered in 308. It has the lightweight handrail and the very nice Magpul PRS stock. Amazing rifle, I have only shot it a few times just to break in the barrel. Unfortunately due to lack of time it just sits in my safe, and I don’t see my schedule lightening up any time soon. It has a very nice Arken scope, it’s their higher end model with Japanese glass. If you want the rifle with scope, scope mount, and bi-pod $1,800. If you just want the rifle $1,400.
