I am working on building an ar-15 and still need a free float tube. I will need one with a barrel nut as part of the assembly. It will need to be a mid length tube.
As I am already over budget, I can't afford to buy one of the fancier models.
Daniel Defense Lite rail 9.5FSP, I'll include the wrench for DD barrel nut. $200 shipped....designed to keep front sight base on carbine gas system and extents past on sides and bottom.
