The pigtail gas tube was designed to solve timing problems for over-gassed 7.5in 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 or builder to use standard Mil-Spec carbine parts for better reliability. Fits all barrels using a pistol length gas system with an outer diameter at or below 1in. The diameter of the outside of the pigtail gas tube loops range from 1.46in – 1.56in. For best fit, the minimum inner diameter of a quadrail or handguard should be 1.6in.

It solved the short barrel gas tube issues, I did have to "tweek" it a bit so ends of tubs were where they needed to be. All good. …………………………………………………………………………………….

Update – Jan 2022, still going good in my AR. Stopped the 7.5 inch barrels "over gassing" it had at the time, and cycle timing is now fine with its install. Its been a fine product for me, I have seen others say otherwise – can't speak for them, I know its worked great on this shorty.

This pigtail will NOT work with 90% of hand rails out in the market. The outside diameter of the pigtail is too large to fit in the inside diameter of most any railed hand guards. It simply won't fit. Only round,or non railed hand guards have a big enough ID to fit over this product. If you're worried about timing, go with a different buffer, and buffer spring.
