Spike's Gas Tube Mid Length Blk

The Spike's Gas Tube Mid Length Black is the OEM gas tube installed on Spike's Tactical ST-15 rifles and complete upper receivers. This mid-length configuration is engineered for AR-platform rifles where balanced dwell time and component longevity are priorities. Mid-length gas systems reduce bolt carrier group velocity compared to carbine-length tubes, lowering recoil impulse and extending the service life of internal components during extended firing cycles.

Built from mil-spec 304 stainless steel with a black nitride finish, this gas tube resists corrosion in harsh environments while maintaining dimensional stability under thermal cycling. The black nitride coating provides superior durability compared to standard parkerizing and reduces light reflection in tactical applications. A stainless steel roll pin secures the tube to the barrel, ensuring reliable retention without galling. The 12.5-inch length and 0.2-inch diameter are engineered to precise AR-15 mid-length specifications, guaranteeing proper fit with matched mid-length gas blocks and front sight assemblies.

This component is essential for builders and gunsmiths assembling or maintaining mid-length AR-15 uppers, patrol rifles, and precision carbines. Mid-length systems are favored by operators and law enforcement who prioritize controllability and component reliability over carbine-length responsiveness. Whether you're building a dedicated marksman rifle, upgrading an existing upper, or maintaining inventory on duty weapons, this OEM-quality gas tube delivers the dependability Spike's Tactical is known for in the aftermarket rifle parts market.
