The gas tube is one of the most important components to get correct when building an AR platform weapon. Typically, a stripped lower receiver is built with the primary intent of housing the AR upper receiver along with some lower parts kit. Helix 6 Precision went out and not only purchased all the major lower receiver OEM gas tube vendors and built Helix 6 own based on the fact that manufacturing a quality direct impingement gas tube is a complex task. What Helix 6 has accomplished with this simple yet solid design is a AR gas tube that will properly fit an AR upper with a short oversized gas block. The design features chamfered sides, a chamfered bolt face and a rounded butt where the gas block would naturally rest against. Our gas tube is designed to fit an AR with a short oversized gas block. If you’re planning on modifying your AR platform after building it, this is a must.

BP –
This rifle plus one gas tube has a nice black finish. The install was easy. It would be nice if companies would start sending a roll pin with gas tubes as well.
No Roll Pin –
Would not recommend unless you have spare roll pins. All other gas tubes I've ordered have included the roll pin. For some reason this product does not. I've got to search my local hardware stores now for an appropriate sized pin before I can complete my build.
