Bootleg Rifle Length Gas Tube Sts

The Bootleg Rifle Length Gas Tube Sts is a precision-engineered gas tube assembly designed for AR-15 rifle-length direct impingement systems. This component regulates combustion gases from the barrel to the bolt carrier group, directly influencing reliability, cycling speed, and overall system balance. The rifle-length configuration is optimized for 16-inch to 20-inch barrel builds where mid-length or carbine-length tubes would result in sluggish or erratic cycling.

Measuring 4 inches in overall length with a lightweight design at 0.06 lbs, this gas tube maintains dimensional consistency across Bootleg's product line while ensuring proper gas port alignment within standard AR upper receivers. The stainless steel construction resists corrosion in field environments and delivers long service life without requiring special maintenance protocols. Installation requires no modifications to existing upper receivers on properly spec'd builds, and the tube interfaces directly with standard mil-spec gas blocks and bolts.

This gas tube is suited for operators building or maintaining service rifles, patrol carbines, and competition platforms where reliability during sustained fire is critical. The rifle-length specification provides consistent dwell time (approximately 150–170ms) that allows heavier bolt carriers and properly weighted buffers to cycle reliably without over-gassing the system, reducing wear on internal components. Whether building from a flat-top upper receiver or retrofitting an existing rifle, this Bootleg component ensures your direct impingement system functions predictably across duty and training scenarios.
