This pigtail gas tube was designed to solve timing problems for 7.5" AR pistols. The pigtail design causes the tube to simulate a more standard cycle time and helps remedy timing problems without patchwork like a heavier buffer, etc. This allows the shooter/builder to use standard Mil-Spec carbine parts for better reliability.
Fits 7.5” barrels only.
**Unfortunately the Pigtail gas tube will not fit correctly under the Phase 5 LPSN™ (Lo-Pro Slope Nose Quad Rail)
The diameter of the outside of the pigtail gas tube loops range from 1.46" - 1.56". For best fit, the minimum inner diameter of a quad rail or hand guard should be 1.65"View full product details

We’ve produced what we believe is the best gas tube out on the market for the AR-15 rifle. Our gas tubes are made out of Mil-Spec 304 stainless steel and then are Melonite coated for greater heat resistance, corrosion resistance, and lower reflection. These gas tubes are not only great for .223/5.56 uppers but are perfect for 5.45 uppers for when you shoot cheap surplus corrosive ammunition. These are the same gas tubes that we install on our ST-15 rifles and all of our complete upper receivers.
