The Zapstrike 20-inch AR-15 5.56 NATO Rifle Upper Build Kit from Davidson Defense offers a durable and reliable solution for gunsmiths and firearm enthusiasts. This kit features a 20" barrel made from 4150 CMV steel with a phosphate finish, boasting a 1:7 twist rate and 1/2x28 threading. The rifle gas system ensures smooth cycling and performance, while the upper receiver, constructed from 7075-T6 aluminum with anodized finish and M4 feed ramps, guarantees strength and functionality.
Complementing the upper is a 15" free float quad rail made from aircraft-grade aluminum, providing a sturdy platform for accessories. The micro low-profile gas block measures 0.75" to maintain a clean profile, and the A2 birdcage flash hider effectively reduces muzzle flash while enhancing accuracy. This upper build kit is ideal for those seeking precision and reliability in their AR-15 platform.
