I'd like to have a SBR upper built with a 11.5" BCM barrel, 9" LaRue, and a .750 Syrac adjustable gas block.

I wanna get the dimpled block and have it pinned to the barrel. Can ADCO do that? I'd imagine that pinning the block won't cause any issue with the gas block.  

I know you pin, just want to make sure this one can be pinned cause it's adjustable.

Here's the block:Syrac Adjust Block

Crap. The block is Melonited. Is that considered a surface hardener? I know ADCO won't pin blocks that have a surface hardening finish.

I guess that's a no?

Sorry for the lateness, yes we can do them, they are much softer than other melonited GB's.

No problem, sorry for chopping at the bit.  interesting to note that they are soft. Hmmmm.
