FPNI, Centurion is what you seek as long as your uppers are DPMS high spec

I have one on a Mega Maten build and I am very happy with it

PSA uses a proprietary height that is extremely close to DPMS low.

Other than the rail and upper not lining up height wise would it work?

I guess as long as you aren't using an optic on it.  Won't look right though.

Fulton Armory had a "low" quadrail that I used as a placeholder until I got the proper "High" one. Wasn't obvious from 10 feet away.

You can stumble upon used stuff.

I picked up this DD 762 Lite 12.0 rail on the ee a few years back. On an Aero M5

And then more recently scored a URX 2. also installed on a M5. I had to buy a barrel nut and wrench from d.wilson.

I wished DD would make theirs again, I’d like one maybe two.
If a 147 grn 9mm at 1000 FPS is the hammer of Thor then a 165 grn. 40 at 1200 fps must a lightening bolt from Zeus!

I just got the Centurion Mk 11 quad rail and it looks pretty good. It's DPMS high rail and matches my Aero M5 upper. The Fulton Armory "Low" rail is now surplus to me.

In my post here I explained how I installed the right, left and lower rails on my Ruger SR762.
