Helpful Positive Review Works great on SBR by Randy, Verified Owner, January 2, 2025
I used this on my 458 socom SBR with a 10.5" barrel. This change the recoil impulse and allowed me to dial in my ejection pattern. The extra burn time with this tube makes a big difference for such a short barrel.

Product Info for Phase 5 Tactical AR-15/M16 Pistol Pigtail Gas Tube For 7.5 Inch Barrels Only

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.image
