Hi everybody, did a little cleaning today and have this YHM free float tube and a few things that go with it. These rails list for $180 on the YHM website. It has been installed once so it does have just a few very light marks where the rails were installed. Honestly you have to look for the marks, it's in great shape.
Included in this package deal is the tube, a YHM jam nut and barrel nut, YHM end cap (brand new in bag) a 12" rail, and two 2" rails, as well as a bunch of rail screws.
Brownells sells the YHM jam and barrel nuts for $32, the end caps are $17, though mine was bought some time ago and the sticker on the bag says $14. :)
So adding it all up, which means everything you needed, front to back, to install this quality FF tube, it looks like about a $240 total retail, plus tax, blah, blah, blah.
I'd be happy to pass it along for $160 shipped. PayPal gift only.
