Magpul rail for URX8"

[Kuponski]

What magpul rails to use on URX8"? Has anyone tried this on AAC 9" upper? Thanks

If you are talking about the bottom (like for attaching vert/angled grip) i used on of magpul polymer 5-slot sections, but had to dremel the very tip of the rail to get it under the curved section of urx...mounts up firm, but rail is different height from front rail section of the urx itself...i attached magpul afg on mine, and it fits/looks great in my opinion...

That's what I'm looking to do. I ordered the L5 11slot rail the holes are 3.25" on center and I think that's what I measured on the handguard. But might be a little to long if it don't work I'll try your way. Does your rail holes line up?
Thanks for your reply!!

I did the same thing. Just trimmed off the end to match the curve. No issues

Ya, the holes match perfectly, and the small insert plates that you bolt into have a slight recess which seats nicely in the urx bolt-holes...will work great with minor shaving of the polymer piece...not much at all, just enough to keep curve from affecting attachment...once you actually get the rail piece and hold it up, you will see exactly what needs to be done and how simple it will be to alter...
