I have a NIB Rguns 6.8 SPC spec II carbine upper that I need to sell. I bought it several months ago and then never got around to building a rifle with it. The upper has never been mounted. It has standard m4 handguards, a single rail gas block, and comes with the charging handle and bolt (I used the bolt carrier in a different project). Price $375 shipped via moneyorder or paypal gift. Might trade for the right rifle, pistol, or shotgun.
