GGP profile question

[Yippeekiay]

So I bought a GGP billet for an ar10 (other) build and have a question about high/low profile hand guards. Generally the tab over the charging handle indicates high/low by being 3/16" or 1/8" respectively. The tab on my receiver is almost 1/4".
Am I going to have trouble finding a hand guard that transitions flat without buying and trying a bunch or is there something I'm missing?
For what its worth, I'm eyeballing this one because I like the barrel nut design..

This might help.

Profile dimensions - centerline of bore to top of rail:
AR-15 - 1.215"
DPMS low - 1.253"
DPMS high - 1.313"
DPMS Target - 1.638"
ArmaLite AR-10 - 1.315"

DPMS G2 is the same as a AR-15

No problem. Grey Ghost says that its uppers are DPMS high. Make sure and measure the tang at the center, the outside edges are usually thicker.

GG is DPMS high.
