Noveske MUR compatible with KAC URX4?

AR/M4 AR General Discussion

Yep. Did a search. Didn’t find anything.

Is there ANY other rail platform that will fit my upper other than an NSR?

Thanks

The new BCM KMR will work. It would probably be your best bet considering the URX 4 installs before the gas block since it is one piece with the barrel nut, I am not aware of any reason the URX 4 wouldn’t fit the Noveske MUR though.

I had no idea I had to search for the KMR when referencing the URX4. Interesting.

Ahhh. Seems you edited your response. Thanks a million for the “guesstimate”.

Yes, the email of a reply to your thread you received would have been before I realized that you were asking about the URX 4 specifically. I got confused since it was not named in the body of the post, I thought you were asking about the KMR.
Sorry
But, to answer your second question, the BCM KMR will work.

Thanks. I need to find something soon so kmr out of the question. I’ll just get an NSR as I can’t get definitive on URX.

Well, you may want to take a look at this video of the URX 4 install. There are no anti rotation tabs the straddle the upper, which is really where the compatibility issues come in with the old style/Noveske MUR.

Yeah. Appreciate it. Just got an NSR though. Hope I like it. Have a Noveske MUR and barrel too. Hopefully it’ll all work well together.

Do the anti-rotation tabs on Centurion rails make them incompatible with the MUR upper?

Only the noveske mur. The CMR will fit fine on a vltor mur-1a.

so u cant install a pinned gas block inside the handguard…means all sr15s from Kac are set screwed only

No, they have a new system displayed at the SHOT Show.
You can pin some of them, but it’s a bitch.
