Is this Daniel Defense Omega rail a true free float system? Why or why not?

I'd like to add some kind of rail to my AR with hanguards, in order to mount a VFG and light. I'd also like to reap the benefits of a true free floated barrel.

I'm attempting to understand what makes a rail system a true free-float rail, vs. a partial free-float.

Bottom line: Is this one a true free-float rail? If not, what is a better option for a rifle with handguards?

Does it touch the barrel or A-Frame/gas block at any point?

If not, then it is free-float. In this case, the Omega rail is intended to be a free-float rail system.

I have no experience in building ARs, so it's kinda lost on me. Someone told me that if the rail allows the delta ring to remain, then it is not a real "free float".

Nope. The delta ring has nothing to do with it, as it does not touch the barrel. If the rail system touches the front sight post or any other part mounted directly to the barrel, then it's not a free float.

When using the Omega rail, it does help to remove the handguard cap which is right behind the A-frame, since it can sometimes rub against the front of the Omega rail.

As a followup question, do you know if that rail is any good?

Fit and finish wise, and so forth?

Used to use a 7" Omega on my old M4A1 build. It's a good rail, but not my favorite. The top and bottom rails are too tall for my tastes, but that is all personal preference.

It's well made and easy to install. The only technical complaint I have is that the screws holding the two halves together have soft heads. Using the wrong size screwdriver and too much force will damage them. My Mk. 18 RIS II rail on my SBR has the same problem, unfortunately.

For drop in FF you might also want to look at the Troy 2 piece FF Charlie or Delta if you have carbine gas and want a thinner hg or the G2 MI 2 piece FF which has several lengths and is $100 cheaper than the Troy and DD. It requires cutting the delta ring though.

-A rail that mounts to the barrel nut and does not contact the front
sight base is one that is considered a "free float rail"
-The Omega is the best compromise in a free float rail when considering
a few things. Cost vs weight vs stability vs ease of install
- Many high quality rails require replacement of the barrel nut.
Thus requiring removal of front sight base & flash hider.
-Lower weight, more stable rail is better, however, cost is higher
and install is a bit more labor some. Not a difficult install, but could
be for one not experienced with AR builds

It's a very good rail and it is not difficult to install. I've had two and I'd use MI again.

In all honesty 16 inch at carbines are 300 yard and in guns designed to shoot 3 moa and that is about it. For what most everyone uses a carbine for worrying about free float is a waste. The . Mil has some people that can shoot an m4 pretty well to beyond practical carbine range with a non free float system. I myself have shot sub 10 inch groups at 500 yards with a rack m16a4 with the standard non free float rail system installed. Don't see how a free float is going to make things much better.
The key to the above groups more than anything was using mk262 match ammo and a great coach calling me wind corrections

I have a 7" Omega Rail on a rifle and it is a true free float. Only touches the barrel nut. It is a very high quality piece, I have just moved on to DD Lite rails on my guns. DD is top notch gear.

This is the best picture I could find of my Omega.

I was looking for a FF rail for my work gun and was looking at the 12.0fsp rail pretty hard. Ended up with a Troy alpha rail instead. It's about half the price and you can put the rails where you want instead of being stuck with the quad rail. I love the Troy and it was very easy to install

Mine is awesome! I've had it 4-5 years, no issues.
