Rifle length +2" gas tube - Policeman - 12-28-2016
On white oak varmint length barrels (26") they use a longer gas tube. Would or could a grendel barrel also benefit from a longer gas tube on a longer barrel? Goal to be higher velocity out of an AR platform.
Thanks

This topic came up a few months ago. I think this is a thread that might help answer your question. General consensus is there is no real advantage over rifle length gas system on 26" 6.5 Grendel if my memory is correct.

Idk if anyone makes one for rifle length setup but if you want more room for gas to expand to delay system you might try and find one of those "pigtail" gas tubes. I know anderson makes one for pistol length systems. I'd think that would add a weird twangy feel every time it fires though 'cause its basically a spring. That and you hardly ever see them so that makes me question their effectiveness as well.

ELGS is needed for .260 Rem and 6.5 Creedmoor in the larger guns, not 6.5 Grendel.
Reason is case capacity and slower burning powders, with more elongated pressure curve going down the barrel, hitting RLGS ports with a lot more pressure than 5.56 NATO or 6.5 Grendel.
