Description
The Spike's Tactical ST-15 Enhanced Mid-Length Complete Upper is a 16-inch, 5.56 NATO / .223 Remington upper assembly with a chrome-lined, cold hammer-forged, government-profile barrel. The mid-length gas system reduces dwell time compared to carbine-length setups, which generally softens the recoil impulse and reduces carrier velocity. The flat-top receiver accepts optics directly, and the F-marked A2 front sight is included.

Detailed Features
The chrome-lined bore is the key durability specification: it resists heat erosion and corrosion better than uncoated barrels, which matters on a 16-inch barrel that will see sustained fire. Cold hammer forging aligns the steel grain with the bore, which contributes to consistent accuracy over the barrel's service life. The mid-length gas system taps gas at a point farther down the barrel than carbine-length, which lowers operating pressure at the bolt and generally improves reliability with varying ammunition.
