I am looking for a short barrel for my SCAR, but it seems like a unicorn chase. Apparently the barrels are "tuned" with their individual gas block, so while the barrel is modular, unfortunately each barrel is tied to a specific gas block. This thread has some particulars: SCAR SBR CQC replacement barrel - M4Carbine.net Forums
I am looking to the CQB barrel, preferably with the Surefire suppressor adapter fitted. If I can find a short barrel, I'll do the SBR and suppressor stamps.
Thanks in advance!
