Honestly don't know - LaRue Tactical Stealth 6.5CM Threaded Barrel

I don't know how good this barrel is because I've been sitting on it trying to figure out the gas tube length. I emailed larue for info and got the vague response "the xl one". So i when to their site and saw the tubes bit only from pistol to rifle length, at least according to the listed items in the picture. So I got a rifle +1 and was still too short. After a week larue sent me an sku number and there i was able to find a rifle+2. But I've already order another from odin works through op. In all the pictures I looked at on op and larue they all show this barrel with larue gas block and tube installed leading me to believe it came with them,as it should. I' probably built 100 ar15s and 10s and had never even heard of rifle +2 gas tubes. This barrel should come with everything in the pictures since it such a niche setup. And I dont care for the so called assistance I've had from larue. I hope when I get to actually shoot the gun it accurate enough to be worth the pain its been getting there. I DON'T LIKE LARUE!!!
