Aero Precision/MAS Defense 20" stainless barrel complete upper (bolt carrier group and charging handle included). Also comes with (1) 10 round mag. Upper only, NOT lower or scope. Just included a pic to show how it looks assembled.
Less than 50 rounds through it. Sells for $680 new and out of stock on MAS Defense site.
Built this rifle last winter for something to do and realized I don't really have a use for it...my loss, your gain!
