AR-15 Mid Length Gas Tube
The United Defense AR-15 Mid Length Gas Tube is a mil-spec direct-impingement gas tube sized for AR-15 barrels in the 14.5" to 20" range. At roughly 11.75 inches, the mid-length geometry delivers a longer dwell time than a carbine system, producing a smoother recoil impulse and reduced wear on the bolt carrier group and buffer components. Stainless steel construction holds up to repeated heat cycles, and the included roll pin makes installation straightforward. A solid pick for AR builders assembling a 16" or 18" upper or replacing a worn tube on an existing rifle.

Description
Features
- Mid-Length Gas System — Approximately 11.75 inches long, sized for AR-15 barrels in the 14.5" to 20" range.
- Mil-Spec Dimensions — Built to mil-spec tolerances for drop-in fitment with standard AR-15 gas blocks, barrels, and upper receivers.
- Stainless Steel Construction — Corrosion-resistant stainless steel stands up to repeated heat cycles and hard use.
- Smoother Recoil Impulse — The mid-length dwell time reduces bolt velocity and felt recoil compared to a carbine-length system.
- Extended Component Life — Softer cycling lowers wear on the bolt, extractor, and buffer system for longer service intervals.
- Roll Pin Included — Ships ready to install with the gas tube roll pin needed to secure it to the front sight base or low-profile gas block.
