For sale is a complete upper from Rainierarms. I have only fired 300 rounds on this upper and cleaned every 100 rounds mostly bench shooting. Everything is off of Rainierarms Combat Series CV16 except it comes with magpul handguard. (5.56 NATO 1/7) I'm asking $430.00 OBO. FTF only and I'm located in Puyallup area but can meet depending on location. (808) 221-1345. Thanks!
