I have a Stag 6.8 Mod II chamber SS 20" barrel upper to trade for a Marlin centerfire what have you. (please no 35s, I have that one). I intended to build a lower for it but got a bad case of Marlin fever now. If the offer is right I can throw in a Nikon 3-9 Buckmasters scope, rings, brass and dies with it too.
