Yankee Hill Machine Co Mid-Length Gas Tube – AR-15 Rifles

This mid-length gas tube is a direct replacement for worn or damaged tubes on AR-15 platform rifles configured with mid-length gas systems. The mid-length system—measuring approximately 9.5 inches from receiver to gas block—offers smoother cycling and reduced felt recoil compared to carbine-length systems, making it a popular choice for 14.5" to 16" barrel builds. Replace your gas tube if you experience cycling issues, visible corrosion, or damage from repeated disassembly.

Manufactured from stainless steel with a black finish to resist corrosion and heat. Installation is straightforward for anyone comfortable with basic AR-15 assembly: remove the handguard, drive out the gas block roll pin, swap the tube, and reassemble. No gunsmithing required, though a roll pin punch set and armorer's wrench are recommended.
