Best carbon fiber barrel made - Helix 6 Precision Carbon Fiber 6mm ARC AR Rifle Barrel

I recently watched a video where some dudes were testing a Cobalt Rifle with a Proof Barrel head to head with a Jigsaw rifle equipped with a HELIX6. The opinions of the shooters turned me on to HELIX6 - all of them said it outperformed the Proof using factory Hornady ammo! At any rate, i picked one up here on OP because its the only place I've found one. I installed it on a Next Level Armament matched billet set with a good trigger and it's by far the best shooting rifle I've ever owned. I can shoot 3/4 to 1/2 MOA (at 100) my buddy shoots better than me and shot 1/4 moa a couple groups. Best of all - the only CF barrel I've shot that doesnt "droop" after getting hot.
