Barrel profile for 18" AR 15?
#3
Call Mark at PF.

Tell him you want a 18 inch rifle gas with .750 gas block size and you want it to be light weight.

Flouting is one way to reduce weight but it won't be as much as you think or as much as going with a thinner profile could give.

Flutes don't increase the stiffness of a barrel they only keep the stiffness of the barrel the same while slightly reducing barrel weight. Think it's like 2 to 3 onces difference, so not much.

Long as you don't rapid fire are get the barrel hot a super thin profile like what JP rifles uses or use to use on their 18 inch grendel barrel is very accurate.

Going to a super thin profile will give you the least amount of barrel weight.
