BCM barrel & Geissele SGB set screw spacing, same?

[khc3]

Pretty straightforward, I want to assemble an upper with a BCM barrel and a Geissele rail. Would like to use the included GB. Is set screw spacing a pretty standard thing?

I'll guarantee you the important hole is. No taint on that hole!

I can tell you that my BCM barrel and Geissele gas block were spaced just right.

The Geissele Gas block will work fine. The set screw under the gas port, is right on the money. The second set screw is slightly closer (less spread) then say, a BCM GB, and this doesn't matter.
