Phase 5 Weapon Systems AR Pistols, Gas Tube, Stainless, Fits 7.5 barrelsonlyase Tool 308, 6061 Alumi Pigtail The Phase 5 Weapon Systems Pigtail Pistol Gas Tube for 7.5" barrels is an excellent choice for your next AR-15 Pistol build. 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.
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"
Fits : Fits 7.5" barrels only
Note : Unfortunately the Pigtail gas tube will not fit correctly under our LPSN (Lo-Pro Slope Nose Quad Rail)
