[QUOTE=Robb Jensen;1006375]It looks great dude! :smiley:

Thanks for getting it together so fast…

22

Think there’s any way to direct-connect the FAG?

23

Actually I think with some time and a dremel / drill you could attach the AFG… Would need to counter sink the holes but I’m sure you could get something that would work. I am in preocess of messing with a MOE Vert Grip and shaving the tabs off to see if I can get a fit directly to the rail. I will post pics…

I held it up in the position shown by the pictures without the MOE rail in place and it felt sweet…

For some, the AFG might be OK on the exisiting rail slots. It’s a little far out there for my style but may work for others.

24

I have a LW mid-legth URXIII from the Silencertalk Lunchbox parts and the tabs on the MOE vert grip fit exactly perfect right in the slots on the bottom of the rail. Haven’t seen the bottom of a III so not sure if they are the same.

I lobbied hard for the LW last year but now kind of wish we’d gone for this one in some ways.

25

The bottom of the III looks to be different from the Lunchbox rail. Only has holes on the bottom and no slots for the MOE tabs. Holes are not threaded like the side holes are…

26

Bumping the thread to keep related information together. Have been reading the comments on the URX III and it has certainly peaked my interest. However, I am looking for something a little different.

On my patrol SBR I am looking to simplify the forend setup while at the same time I would prefer to stick with KAC. Anyone heard any rumblings if the simplified and lighter design of the III will find it self in a carbine varient which I could use to lighten up and simpliy my Commando?

27

I have heard that there will be a Mid-length URX III sometime in the future, but nothing certain on the carbine length. For as short as it is, I don’t see a huge advantage to doing the carbine length URX III - how much weigh are you really saving?

28

The 10.25" (ish) Midlength URX’s work on the 11.5" bbl’s with Low Profile Gas Blocks.

We are considering selling the 8" URXIII, but AAC is buying them as fast as we can build them, so not right now.

29

Thanks.

Are you still planning on making a 13" URX? I remember a while back you had said something about potentially making one to cover a 14.5" barrel.

30

Thanks Kevin. Will keep my eyes and ears open should they become available. Much preferring that option to DD in a Mk18 setup.

31

Yes the 13" plus URX is under discusssion, however still nothing finalized

32

My absolute favorite rail. My only complaint is I wish the front sight was spring loaded instead of needing one hand to push the button and another hand pull the sight up.

33

is there a vendor here that will install a URXIII and remove my URXII and modify the gas block for URXIII. I have long arms and need just a longer rail thanks.

34

Robb at Virginia Arms will do it I am sure. The barrel wrench issue is a real downer with these rail systems.

35

So how does one attach a vertical grip on this? Otherwise, how is one supposed to get a good positive grip on the rail without blocking an attached PEQ?

36

You can add Magpul segments to the bottom handguards.

37

Awesome thread. Any of you guys who have been messing around with adding rail sections to your URX III, have you guys found a great solution. I believe KAC has come out with low profile rail sections compatible with the URX III’s. Has anybody played with these? I haven’t seen much about them as I believe they were available as of October 2012. Kevin B, is this correct? Thanks all.
