Spike's Gas Tube Carbine Length Blk

The Spike's Gas Tube Carbine Length Black is a mil-spec gas tube engineered to the same standards that Spike's Tactical installs on their ST-15 rifles and factory upper receivers. This is the critical component responsible for directing expanding powder gases from the barrel back to the bolt carrier group, making reliable gas tube selection essential for consistent cycling and longevity in any direct impingement rifle platform.

Built from mil-spec 304 stainless steel with a black nitride finish, this gas tube resists corrosion and wear even under high-round-count firing schedules and harsh environmental conditions. The black nitride coating provides superior hardness compared to traditional parkerizing, extending service life in both wet climates and high-temperature shooting. A stainless steel roll pin secures the tube assembly, ensuring reliability without degradation. At carbine length, this tube is optimized for standard 16-inch M4-pattern barrels, the most common configuration for tactical rifles, duty rifles, and training platforms.

This is the ideal replacement or upgrade for anyone building or maintaining a quality AR-pattern rifle. Whether you're assembling an upper receiver, performing routine maintenance, or restoring a rifle to factory Spike's specifications, this gas tube delivers the precision engineering operators and gunsmiths expect. Used by Spike's Tactical in their own factory builds, it represents a proven choice for anyone who demands consistent performance and durability in a core rifle component.

Gas tube replacement is straightforward during upper receiver assembly or maintenance and requires no special tools. Keep a spare on hand for field maintenance or builds in progress—this is one of the most reliable components to have backup inventory of.
