There’s two things I think about when I hear ‘Omega’.

This:

81iLZKQyLaL._SL1256_

And this:

Many will disappointed to note that I’ll be looking at the latter in this blog. But fear not! I am listening to the former as I write…

The Daniel Defense Omega occupies a very special place for me, because the Madbull version was the very first RIS I installed on my very first PTW.

Now, with big thanks to Tom – Team Cobalt‘s C03 – I’ve acquired an RS one.

The first thing you notice about the Omega is its cross-sectional profile. It’s kind of oval, with relatively tall 12 and 6 O’clock rails and tighter 9 and 3 O’clock ones:

omega_2It’s made this way to mimic the profile of the OG M4A1 plastic hand guard.

The Omega was designed as an easy to install free float rail. Free float means that it doesn’t affect the barrel in any way, potentially improving accuracy in the RS.

The way the rail fits is ingenious, with no need for a proprietary barrel nut.

It envelopes the standard barrel nut and locks-on using four allen grub screws (imperial, naturally).

Here’s the business end, the rear of the rail. Note the four grub screws (and the wide open gas tube void at 12 O’clock):

Here’s one of a grub screw from the front. Behind it is the collar which helps keep the barrel nut captive within the rail. When tightened, the grub screws push against the barrel nut. This tightens the collar against the rear of the barrel nut and the rail is thus locked-up, solid.

The Omega is a two piece rail, which is held together by four slotted screws – two on each side:

The screw holes are helicoils; threads are not tapped directly into the 6061-T6 of the rail:

The integrated QD sling swivel point is a nice feature. It cuts down on additional hardware and is rotation limited:

Lastly, I didn’t notice this at first (because I’m a bell end) but as pointed out by my mate and fellow Omega-phile Neil, this rail exhibits the newer DD address:

How about pics of the Omega in use, Rich?

…you may demand.

You’ve taken us this far and this is way too much detail for yet another shitty civ build!

…you may add.

Well, I do like mil and civ builds (and I especially like MilCiv ones).

There does indeed exist a really inspiring Block 1.5 photoset which features the Omega. I’ve included it below.

Other items to note in the pics:

  • Aimpoint Micro T1
  • LaRue Aimpoint Micro mount
  • Vltor Clubfoot stock FDE
  • Tango Down pistol grip FDE
  • Tango down vert grip FDE
  • Pmag FDE
  • Surefire hider
  • MATECH rear BUIS
  • No paint (heresy)
  • No flashlight (none that I can see, anyway)

It’s often said that AFSOC PJs have some of the most innovative blaster variations and I believe these pics (likely from 2012) demonstrate that.

Really interesting post on ar15.com, from a guy who is known to know what he’s talking about:

AFSOC has some of the most interesting variation in their weapons – how much of this is related to the fact that they “play with others” a lot is hard to say – but I’ve seen them with a lot of different types of equipment.

I think there’s a lot of variety as to what individual STSs (Special Tactics Squadrons) choose to equip with. The other thing to consider is budget – in general, the Air Force tends to play with bigger ticket items – so they have relatively bigger budgets per man, and AFSOC is a pretty small component.

NSW doesn’t really have to go outside of Crane too much, since the Navy “owns” Crane – what NSW wants, they can just ask for through NSWC-Crane, and it becomes “standard” for SOF. NSW is also pretty small compared to the rest of the Navy.

The Army has the largest SOF components – plus it has to split their SOF budgets between 75th INF and the Groups, meaning they have to be a lot more frugal about expenditure per soldier, unit funds are tighter, and units are encouraged to “order out of the catalog” (SOPMOD items) as much as possible.

As for the MSOBs, well, not only are they small, but the Marines are always digging for money, no matter who you are.  

That being said – I’ve seen a lot of Surefire suppressors and muzzle devices used on various AFSOC M4A1s.

I think the DD Omega 7.0s have been pretty limited to that one unit (forget which those photos are attributed to). Furthermore, that particular unit seems to issue:

Tango Down BVG-46 (Surefire pocket) and Battle Grips in FDE, as well as FDE Vltor Clubfoots.

Someone there is probably an ARFCOMer, too – because optics are T1s and M2/3s in LaRue mounts with Aimpoint 3x magnifiers and twist mounts.

They seem to be running M600C Scout lights, too.

I’ve also seen various AFSOC / STS folks running M68CCOs (Aimpoint CompM4), as well as EOTech 552s. Their carbines I’ve seen doument range from indistinguishable from other componets’ weapons to “M4A1s” that were actually XM177 lowers with two position vinyl acetate stocks running RX01NSN Reflex sights, to HK416s, and beyond.
