Rock River Arm RRA New mid length upper 5.56 Listing ID: 3349748

This is a new Mid Length upper that has been in my safe unused and it needs a new home. Pics still show some of the packing goo. This is a mid length gas system on a 16" barrel 1/9" twist rate, also has BCG. Cash only. Meet at the Kroger in Henderson, Once a month I go to Sam's in Longview if that helps.
