Yes sir and no adjustable gas block because it wouldn't fit without touching the handguard. I'll switch to the gas key adjustable one per your recommendation to others if it's warranted but initial testing says it's not. I can play with buffer weights and springs already if anything seems off so will try that first if anything is seen once I start pushing appropriate charge weights. I'm ramping up, not going full blast out of the gate.
