The AR-15 5.56/.223 20 Stainless Steel Diamond Fluted Tactical Upper Assembly is a key component to consider when customizing your AR-15 rifle. CA and NY compliant.
Features:
1. Barrel: The centerpiece of the assembly, the barrel, is crafted from stainless steel and comes in at 20 inches long. The barrel chamber supports both 5.56 NATO and .223 Remington rounds. The steel makes the barrel corrosion-resistant, which significantly extends its service life.
2. Diamond Fluting: The barrel has been diamond fluted. Fluting refers to the process of removing material from the barrel, creating ridges. This design increases the barrel’s rigidity and assists in faster cooling during rapid fire.
3. Gas System: The assembly has a rifle-length gas system. The placement of the gas block and tube greatly affect the firearm's recoil and cycle rate.
4. Finish: Stainless steel offers not only excellent strength but also an elegant, modern aesthetic.
5. Handguard: A full-length handguard is generally provided, usually featuring M-LOK rail systems for accessory attachment. The design may vary depending on the model.
