White Oak Armament Gas Tube Extended Length +3'' (18.160'') Stainless Steel
White Oak Armament
The White Oak Armament Gas Tube Extended Length +2'' represents a precision tuning option for AR-15 builders working with longer barrels and high-performance builds. This stainless steel gas tube measures 17.160 inches—two inches longer than standard rifle-length gas systems—and is designed to optimize the relationship between barrel length, case capacity, and gas system dynamics. When properly matched to your rifle's configuration, an extended gas tube can improve brass longevity, enhance reliability, and sharpen accuracy on the range or in the field.
Extended-length gas systems aren't a universal upgrade; they're a deliberate choice for shooters building custom AR-15s with barrels long enough to benefit from the adjustment. The goal is finding the sweet spot where dwell time and gas pressure work in harmony with your specific barrel and ammunition combination. White Oak Armament manufactures this tube in stainless steel to resist corrosion and handle the thermal cycling that comes with serious shooting sessions.
Installation and tuning should be done thoughtfully. We recommend consulting a competent gunsmith to determine whether a +2'' extension is the right choice for your barrel length and intended use. Get it wrong and you may struggle with reliability or accelerated component wear; get it right and you'll notice tighter groups and happier brass. This is the kind of upgrade that separates dialed-in builds from guesswork.

This gas tube is designed for longer-barreled AR-15 builds where a standard rifle-length gas system would result in excessive dwell time or reliability issues. Consult a gunsmith to determine the optimal gas system length for your specific barrel and ammunition combination.
When properly matched to your rifle's configuration, optimizing the gas system length can improve accuracy by ensuring correct dwell time and consistent cycling. However, installation and tuning must be done correctly—improper matching can have the opposite effect.
You receive the White Oak Armament stainless steel gas tube. Installation into your rifle's gas block and tuning to your specific setup is a task for a qualified gunsmith.
Stainless steel resists corrosion from the harsh thermal and chemical environment inside the barrel and gas system, ensuring durability and longevity through extended shooting sessions.
