This line of gas tubes from Voodoo Innovations is a great replacement for your old original gas tube. The VDI gas tubes are compatible with mil-spec and non mil-spec upper receivers making them a great option for that new build. While they are constructed from stainless steel, Voodoo Innovations coats them with their proprietary LifeCoat technology, which provides superior durability, lubricity, and corrosion resistance. The LifeCoat coating also gives the gas tubes a distinct black color that either blends in with a parkerized barrel or stands out against a stainless one.
Once the Gas Tube is installed you can expect it to appear shorter. This is because the gas tube sticks in a little ways into the upper receiver. If measured after the installation, the length from the barrel extension to the should appears as follows:
- Rifle Length is approximately 13.241"
- Mid Length is approximately 9.866"
- Carbine Length is approximately 7.866"
- Pistol Length is approximately 4.846"
- Machined to exceed all MIL TDP Specifications
- Enhanced using a proprietary LifeCoat Treatment
- Increased durability, lubricity, and corrosion resistance
