That gas block will work on this barrel, however you would have to dimple the barrel first for proper security.

From Faxon’s website: But What About Your Gas Block? It Uses Set Screws?

It does, but the dimple is not needed.

We use three set screws instead of the common two.
Faxon uses "flush cup" screws. The cupped screws each "bite" into the steel and when combined with the recommended thread-locking compound (either red Loc-Tite or RockSett), the gas block is locked into place.
