Creedmoor uses an AR10 vs an AR15. You can buy plenty of mags for the difference.

So longer than rifle length? Tell me more.

... barrels use the somewhat unusual “extra long” gas system, which is two inches longer than the standard “rifle length” gas system normally used with 20″ barrels. The longer gas system coupled with large diameter port settings reportedly increase dwell time while reducing the port pressure.

Different gas-system lengths come into play as bullets move down their barrels, reducing the pressure behind them. A longer gas tube corresponds to a gas port placed farther down the barrel (toward the muzzle), yielding lower port pressures, since there is more room for the expanding gases behind the bullet as it passes the gas port. Once the bullet leaves the muzzle, pressure drops off. Therefore, a gas port closer to the muzzle reduces the amount of time that highly pressurized gas has to act on the operating system after the bullet passes the port, usually referred to as "dwell time." When comparing two barrels of equal length—but with different gas systems—the longer gas tube will produce a reduced dwell time. The practical results are usually slower bolt-carrier movement and a slight reduction in felt recoil. The latter facet is quite apparent to someshooters but can go completely unnoticed by others. I regularly shoot all three gas-system lengths, and I can feel the difference in otherwise-like barrels.

Maybe they ran their mouths off before they thoroughly tested it and found something. I will wait awhile and see what happens. Wrapped my money up on another toy anyways so will have to wait.

Savage
Ballistic Advantage (barrels & uppers)
Barrett (semi-auto & bolt gun)
Seekins Precision
CMMG

Nice list. Just checked seekins and don't see anything on their site. Got a link? I did see one bolt rifle but was very expensive. Will be checking others on your list. Thanks.
