Olympic Arms AR-15 16inch barrel clean original owner in Seattle, Washington For Sale

I am selling my Olympic Arms AR-15 rifle. Very clean with maybe 3 magazines shot through it the entire time I had it. I am the original owner and have the original sales receipt from Beavercreek Armory in Hillsboro, OR. Has a aftermarket stock installed by Beavercreek and one OEM magazine and one aftermarket polymer magazine. All manuals and the original lockable Olympic Arms carrying case are included. Girlfriend doesn't like guns in general, but particular these kinds, so it must go. $800.
I also have a new Federal 420 round 5.56x45mm ammo can from Cabelas (back when they actually had stuff in stock) for sale. No ammo ever removed from it. $180.00.
