Upper is almost done. Just missing the real optic and some other goodies. Also waiting on the stock to get here to finish the lower.
PS - URX4's are a pain to install ESPECIALLY if you have a pinned gas block. I finally gave up and dremeled a hole in it to punch it through. Now to see if a 6.5" 1:7 twist barrel will stabilize 220gr....

Looks awesome - can't wait to see the whole thing!!
You guys made my year by all the stuff you and AAC had at the Machine Gun Melee - it was a blast!. I intend to make the drive to check out your store before too long.
Jake, what barrel and gas block did you use? Upper looks good buddy.
Yeah, the install video KAC has on their channel even shows them installing one with a set screw gas block. Made me think about how you would put one on with pinned gas block?
I actually wonder if that's one of the main reasons they use a castle nut to secure the the Mod2 gas block? I know they claim it keeps from cutting the barrel and seals better, but still. No way mass production would happen with efficiency using the URX4 and trying to fish set screws or driving pins in somehow with that rail.
I should have my new barrel tomorrow. First one had some issues.
I will also show how I used a pinned gas block.

This is my only complaint about the URX4. It will work fine with some set screw gas blocks depending on the gas system length and set screw spacing on the block. But if it doesn't all line up perfectly with the keymod slots, you pretty much have to mill a slot in the rail. Pinned gas blocks can be done, but it's like building a ship in a bottle. For pinned blocks, it's basically a requirement to mill the rail. Not ideal.
I suggested a while back that the new gas system was designed as an end-around solution to the complications that result from the integrated barrel nut design of the rail. But KAC insists that they were designed in tandem. The gas system and IBN are certainly typical of KAC innovation and they work well together. But I won't use the URX4 on a build because of these issues. And that's saying alot for this admitted KAC whore.
Lol, yeah awfully suspicious they were designed in tandem.
You know there was probably a design engineer all pumped up about the URX4. then went to install it and was like WTF? oops, lets "innovate" that gas block...lol
Yeah, as a system, I love the mod2. But as a stand alone rail, I'm not a big fan of the URX4.
