rob s,
Could you expound on why you would not use an Omega, given the choice for an application where the rail will extend past the gas block.
Thanks, Virgil

It's just that the OMEGA was designed as a workaround for those who CAN'T remove the FSB (whether to follow rules or in the instance of a permanently attached muzzle device). in other words, it's a compromise solution (and we have to assume the performance may be marginally compromised too).
there are other FF rails out there designed specifically for FF use. If you have the flexibility to remove the FH and change the GB, then look to the more robust solutions form DD, Larue, etc.
to add: I personally use a DD Omega rail on my LMT

I am big on reducing joints and parts in any system. This comes from my "day job" in construction where every joint and every part is just another potential failure point.
The Omega was originally intended as a solution for those that wouldn't (due to laziness), couldn't (due to lack of tools or skills, or a permanently attached muzzle device) or shouldn't (due to department or agency restriction) remove the FSB and barrel to install a rail. The trade off is that it has more parts and joints than an M4 or Lite Rail by the same company. Dimensionally it offers no real advantage over the other DD offerings.
Model | Height | Width | ID
M4 | 2.43 | 1.94 | 1.45
Lite | 2.43 | 2.06 | 1.23
Omega | 2.43 | 1.90 | 1.10
In addition to the above, I find the best type of low-profile gas block to be one where the stock front sight base is removed and shaved down. To do this for the Omega you have to get very aggressive with this shaving due to the small ID, which is in turn a result of the modular nature of the rail system. Again, if there is a limitation such as a non-removable muzzle device then the FSB can be ground down in place (gotM4 has done this at least once in the past and posted pictures here) and the Omega might be a viable solution.
In short, if there is no compelling reason that the front sight base and barrel nut cannot be removed, I would go with the M4 or Lite. Further, if the reason the FSB and nut can't be removed is a "shouldn't" then I hardly think that cutting down an FSB or swapping it out for a low profile would be an option.
The gun held up fine after 1780 rounds this past weekend.
I will go on record as saying that this kind of a build is probably less than ideal since like Rob said, there are quite a few extra parts on these rails.
The quality is fantastic but we all know that the second you add more shit you also add more failure points.
I beat the hell out of the rifle this past weekend and while it passed with flying colors im interested to see how long its going to continue passing these kinds of torture tests.
Only time will tell.
If i wasnt so married to the profile of the Omega rails i would definitely switch it out.
My 7.0 Omega Rail has held up great. But I have two rules: First, I do not intend to mount a sight on top of it, if only because there's a theoretical possibility to be a slight offset from the upper receiver. I'm not interested in any sight that far out anyway. And, second, I mount my vert grip not past the center point to reduce torque/leverage against the delta ring and mounting hardware. With this in mind, I think the Omega Rail is a phenomenal product and fully capable of field use. I mounted mine on a 6920 that I had no interest in breaking down its factory-assembled, semi-perm components.
