So a quick tid bit today, I finally got some extensive use out of my SF optimized bolt carrier today. Had a 3 day entry class this week, and on the final day, I decided to use one of my personal carbines for the live fire drills. Decided to throw in the SF carrier and a Dead Air Sandman K at the end of a CMT build with a 10.5 Ballistic Advantage Barrel. Gun has no other gas mitigation systems and no adjustable gas block.

Barely any gas in the face after 600 rounds. It was a pleasure to shoot and I would say there is no more gas in the face than a non-suppressed gun. I'll need to run the gun a little more, but so far, I'm impressed with the results and looking forward to building another dedicated suppressed gun around a 2nd SF carrier I have.
