Amazing free float tube - ATI Outdoors AR-15 8-Sided 15in. Free Float Forend & Slotted Barrel Nut

I am using this on a custom build with 24" barrel and large scoped AR. I also wanted to be able to have iron sights for shots under 100 yards. This system allows me to have the best of both worlds, a scope and 45 degree mounted iron sights. I'm considering putting these on all my AR's, just to have all the options for mounting stuff.
Pros: Free Float, 8 Rails, Light weight, appears rugged
Cons: Have to buy picatinny rails separately
