Finished in official Storm Trooper Imperial White.
Thanks to its official Storm Trooper White Cerakote finish, this AR-15 upper looks as good as it runs. Coupled with a precision-machined barrel, the Storm Trooper upper is made to provide high performance.
Its H-Series Cerakote provides one of the most durable, corrosion-resistant, and chemical-proof coatings in the gun world. The H297 Storm Trooper White coating itself was made to be the brightest, whitest ceramic coat -- this is an upper that stands out like a Trooper's armor.
The barrel was made to offer maximum accuracy. It's forged from 4150 CMV, rifled with a quality, precision-machined carbide rifling button, then quenched with a QPQ Nitride conversion coating that ensures your rifling's tolerances stay exact, while promoting high heat resistance and easy cleaning.
Inside, the standard carbine gas system is replaced with an more optimized mid-length setup. This finely tunes dwell time to reduce felt recoil and carbon fouling, while ensuring the BCG cycles with better timing for more reliable performance.
