Spike's Gas Tube Rifle Length Blk

The Spike's Gas Tube Rifle Length Black is a mil-spec AR-15 gas tube engineered to the same exacting standards that Spike's Tactical installs on their ST-15 rifles and complete upper receivers. This is the precise component that meters propellant gas from the barrel into the bolt carrier group, making it critical to reliable cycling and consistent performance across a wide range of ammunition types and environmental conditions.

Manufactured from mil-spec 304 stainless steel with a durable black nitride finish, this rifle-length gas tube resists corrosion and carbon buildup even during extended range sessions or field deployment. The stainless steel roll pin ensures secure attachment and repeatable function cycle after cycle. The nitride finish offers superior hardness compared to standard blued finishes, providing both aesthetic appeal and functional longevity in harsh conditions—from wet coastal environments to dusty desert operations.

This component is essential for anyone building or maintaining a rifle-length gas system AR-15. Whether you're assembling a patrol rifle, training platform, or precision carbine, proper gas tube quality directly impacts reliability and reduces maintenance intervals. Operators and gunsmiths specify this tube because it meets mil-spec tolerances without premium pricing, making it the practical choice for serious shooters who demand verified parts rather than unknown alternatives.

Rifle-length gas systems offer extended dwell time compared to carbine-length tubes, which translates to smoother operation with suppressed fire and marginal ammunition. This Spike's tube is dimensioned for standard rifle-length configurations and will not fit carbine or pistol-length systems—verify your upper receiver specification before purchase.
