BOOTLEG RIFLE LENGTH GAS TUBE STS

Description

The Bootleg rifle-length gas tube is a straightforward replacement or build component for AR-platform rifles running rifle-length gas systems. A rifle-length gas system taps propellant gas from further down the barrel than carbine or mid-length configurations, which gives the bolt carrier group a longer dwell time and spreads the recoil impulse over a greater portion of the firing cycle. The practical result is a softer, more gradual push rather than the sharper snap associated with shorter gas systems—a difference that becomes noticeable over a long range session or when running suppressed.

This tube ships in Bootleg’s silver finish, which distinguishes it from standard phosphate or parkerized steel tubes and makes it easy to confirm installation at a glance during a build or inspection. The finish is part of Bootleg’s design intent, not an afterthought, so the designation is carried through in the part number itself.

Bootleg is a veteran-owned manufacturer that focuses on AR-15 components, and this gas tube fits that same ecosystem. For builders pairing it with a standard front sight block or a low-profile gas block, the rifle-length dimension dictates handguard and gas block placement, so confirm those measurements before ordering. It is a purpose-specific part: if your barrel and handguard are already spec’d for rifle-length, this is a direct fit with no modification required.
