    20” 6.5 Creedmoor Barrel Gas

    I’m in the research phase of doing a 6.5CM AR build. I’ve read that with barrel lengths longer than 22”, a ‘rifle+2’ gas system is recommended due to the cartridge being higher pressure than .308. Is an extended gas system also recommended for 20” as well? Thanks.
    Good equipment is no substitute for good training.

    No not necessary. On a side note, I have a 24" standard rifle gas that runs fine too, so it isn't technically necessary even for the longer barrels, although it is probably more "optimized' to run the rifle+ length.
