I have a used TROS 9" 3-lug barrel that I'd like to trade for a 5" TROS 3-lug. This barrel has been cleaned after every use and works perfectly. It is in great condition. I got it used and have put a few hundred rounds through it but the rifling looks great. I no longer need the accuracy of the 9" and just want to shorten my SBR by 4".
I'm willing to trade it straight up for the 5", or sell my 9" if the price is right.
