Phase 5 AR15/M16 Pistol Pigtail Gas Tube AR-15
The pigtail gas tube was designed to solve timing problems for the 7.5" pistol barrels. Using a gas tube that is almost the length of a rifle gas tube, making the gas take longer to reach the gas key. Simulating a more standard cycle time and helps remedy the timing problems without patchwork like heavier buffer, etc. This allows the shooter/builder to use standard Mil-Spec carbine parts, making it more reliable, easy to maintain and more predictable.
*Fits 7.5" barrels only*
Made in USA
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".
