G&P SR-25 URX Rail compatibility/install?
 

Hi guys,

So I was scrolling through Huang's page and the G&P URX rail caught my eye.

I was looking into installing it on an ICS M4 but as I was doing some research I stumbled upon this video on YT and the guy going over the install was talking about a 'lugnut screw' that goes onto the receiver's threads.

Here's a timestamped link to the specific part I'm talking about over on YT: Installing KAC URX toolessly airsoft - YouTube

I emailed Huang already but have yet to receive a reply. Do URX kits come with that piece, or would I have to source one out from G&P?

Thanks

I guess I'm SOL, huh?

The G&P URX comes with that part.

use this G&P tool, the installation is more easily.
