Clearing out some spare parts. I have two carbine free float tubes with barrel nuts that I don't need anymore. Both are anodized aluminum, knurled and one has slots. I can't find a mark anywhere on either. I am asking $38 shipped for each or $70 shipped for both. I also have two low profile rail top .750 gas blocks that do show some slight attachment marks $10 each plus shipping. Make an offer on one piece or the whole bunch if you like. I can send pics.
We live in the land of the free because it is the home of the brave. THANKS to all our military and LEO for the job you do.
