Comes with a gas tube by Ar, Verified Owner, April 19, 2023

Product Info for Helix 6 Precision Carbon Fiber 6mm ARC AR Rifle Barrel

Building on the industry standard that started it all, Helix 6 Precision Carbon Fiber Barrel for 6mm ARC AR Rifle delivers exceptional accuracy from a lightweight and hand lapped bore that reduces fowling and increases accuracy.

These barrels are up to 50% lighter than a steel barrel of equal contour - Which means they are the perfect upgrade for your favorite 6mm ARC rifles.
