The folks over at SIG SAUER have been busy. Following the introduction of their flagship MCX rifle line they haven’t been able to keep up with demand. Naturally this has had a bit of a negative impact on accessories that were promised to be “on the way,” including the 9″ replacement 300 AAC Blackout barrels. Word comes from the horse’s mouth that those barrels are officially 30 days from shipping to distributors, and the 11″ 5.56 barrels are available right now.



  1. Bah ha ha. You let me know when that 9” 300 blk piston set up is thoroughly tested and proven. In the meantime, count me as skeptical.
