20” inch 5.56/.223 cal. M16/M4/Ar15 Bull barrel for sale in Austin Texas

$100.00

I have a brand new never used 20” inch 5.56/.223 cal. M16/M4/Ar15 palmetto Bull barrel for sale was going to be used for a M16 build I did a while back and I ended up buying a complete upper instead so I just held on to this one for a new build but I don’t think I will use it so I’m selling it or I am also open for trades something smaller and/or something in .300 black out
