Agreed. A few more expensive doo-dads and she'll be done!

Got 'em!

Got 'em!

And a KAC carrier which is shamefully not etched! It's like having a shiny new pair of Jordans with no swoosh!

Got my KAC Lower approved, so my SR-16 based upper gun is done.

Unless I get a FDE T2.

Have you shot that SR-16 upper previously? Seems like reliability has been hit and miss with those uppers. When they work, they work great, but when they don't, lots of mailing back to KAC.

I only have 3 mags through it. Was waiting for my Form 1 to be approved.

I'm headed to the range next Monday, I'll let you know more.

Didn't know where to post this question and can't seem to find an answer. I will be getting a KAC SR15 MOD1 with a URX 2 rail. I've always loved the URX 3.1 rail, how hard is it to swap rails? Do they utilize the same barrel nut or do I need their barrel nut wrench?
Finally venturing into the KAC world and this trade just fell into my lap. I'll be honest I don't like their mlok or key mod rail.
Hoping to get a good deal this forth of July for a urx3.1

If memory serves, the URX 2 and URX 3/3.1 use the same barrel nut. The URX 4 has a different one.

If you're going go from a URX 2 to a URX 3.1 good luck getting that gas block off. I'm guessing it's a Mod 0 if it's got a URX 2. The URX 3.1 was the Mod 1.

Damn I have to take the gas Block off? Not like others where the rail slides over it and you lock it down? I just found two urx3.1 rails for sale is it more of a hassle to switch the rail out?

The problem is the nut. The URX is a weird animal where it actually screws onto the receiver and then the nut is essentially a jam nut. So once you unscrew the URX nut (with the correct wrench...after breaking the thick soup of Loc-tite), you then have to unscrew the top rail. Then both the nut and the rail slide forward over the gas port.
