AR-15 Pistol Gas Tube
The United Defense AR-15 Pistol Gas Tube is a stainless steel, pistol-length replacement gas tube for short-barreled AR-15 builds running barrels 10 inches or shorter. Machined to MIL-SPEC dimensions at roughly 6.75 inches, it drops into any standard pistol-length gas block and pins down with the included roll pin. The precision bend and corrosion-resistant stainless construction deliver reliable gas flow to the bolt carrier under hard use. A solid choice for AR pistol builds, SBRs, and replacement work on existing pistol-length direct impingement systems.

Zero issuesThrew this on my 7.5 inch pistol build and cycled through about 300 rounds of cheap brass ammo with no hiccups at all. Fit was tight and lined up perfect with my low pro gas block, didnt have to mess with it at all. For the price I honestly expected less but this thing delivers. Shipping was fast too, had it in 3 days which was a pleasent surprise.
Great value for the price
