Works well - NcSTAR AR-15 Free Float Quad Rail Handguard/Rifle Length

Comes with all the necessary hardware to install it..My Armorers wrench wasn't a perfect fit to the barrel nut. The spacing on the holes was off just a tiny amount. Still I managed to get the pegs on the wrench to go in the holes with a little wiggling. It looks pretty good, although I now wish I didn't go with a quad rail,It looks kind of bulky and doesn't fit the theme of the rifle I'm building, but that's no fault of the product. The top quad rail lined up perfectly (horizontally) to the rail on my DPMS lo-pro, but was slightly wider. Not really enough to notice unless you really study it. The threads on the barrel nut and inside the tube are cut well and threaded on with ease. Seems plenty well built and I'm happy with the purchase, especially considering the low price.
