Testing the waters. I've got a lightly used safe queen... FN FS2000 Space Gun. Mine is the Original model with the optic. You can easily remove the optic and use the rail if you like. Mine is Black, Very lightly used and in great shape. It has an upgraded metal charging handle and an Urban ERT sling. (the best sling for the FS 2000) Looking to sell for $2500. Possible trades for high quality AR style guns, uppers, lowers, 308 etc... Please don't bother me with franken guns or oddball stuff. I've got good reputation here and on Arfcom.
