I have had this "thing" for a 14.5 middy. I cant decide what I should do though, should I just buy the barrel and tube and convert my 6920 or should I trade/sell my upper and get a BCM? I dont like mixing and matching on good guns but I cant afford to build/buy a complete upper. I know the difference and the difference wont make a difference at the distances I shoot, but I will build a rifle length one of these days. Wanna kill these ads? We can help!
