TeleStratMan Posted July 20, 2019 Report Share Posted July 20, 2019 I'm getting ready to purchase my barrel and I notice Rifle Length + 2 for the gas tube. Is this setup necessary to operate the AR10 / DPMS308 in the 6.5 CM configuration? Thanks. Quote Link to comment Share on other sites More sharing options...

TeleStratMan Posted July 20, 2019 Author Report Share Posted July 20, 2019 Looking at several different brands and some state the rifle + 2 and some don't. Quote Link to comment Share on other sites More sharing options...

Don't leave Faxon out of the mix, though. BA, Faxon, and WC are what I would have recommended. Rifle +2, don't do that on a 20" barrel, if that's the way you're leaning. 20" doesn't benefit from Rifle +2, and we've seen one here that didn't work. Had to up the gas port size because of it... It's a Dwell Time thing. 22" and 24" can benefit from R+2 gas systems, and soften the recoil. It mitigates the longer Dwell Time that a Rifle gas system on such a long barrel would have, which would increase how harsh it feels... But, it's still 6.5 Creedmoor, so it's not gonna kick you like .308 Win would... Quote Link to comment Share on other sites More sharing options...
98Z5V Posted July 20, 2019 Report Share Posted July 20, 2019 A Criterion or a Fulton Armory barrel would also be a very excellent choice, right up there with the other 3 I mentioned above. Quote Link to comment Share on other sites More sharing options...

Thanks for all the info. I will take a look at the Criterion Barrels. Could I use an adjustable gas block to compensate for the lack of a longer gas system?

You haven't explained that yet, and that drives the whole train... Quote Link to comment Share on other sites More sharing options...

98Z5V Posted July 20, 2019 Report Share Posted July 20, 2019 With a 6.5 Creedmoor, you can crush 500 yards with a 16" barrel. I have a 20" barrel on my .260 Remington build (the theoretical twin that 6.5 Creedmoor came from), and my handload is supersonic to 1500 yards. So far, it's laser accurate at 845 yards, repeatable, and I've had it at 1000 and 1100 yards very, very effectively. If 500 yards is the ultimate goal, you don't need 22 or 24 inches of barrel to lug around. Are you hunting 500 yards, or punching paper and banging steel at 500 yards?

TeleStratMan Posted July 20, 2019 Author Report Share Posted July 20, 2019 My "lug around" rifle is a 6.5 Grendel with 20 inch barrel. Back to the original question : Adjustable Gas Block or Not? Quote Link to comment Share on other sites More sharing options...

Back to the original question : Adjustable Gas Block or Not? A properly balanced gas system and recoil system will not need an adjustable gas block. That changes if you are shooting suppressed.
