Build your next AR pistol or SBR with a foundation of quality. The Palmetto State Armory (PSA) 10.5″ Nitride Upper is engineered for enthusiasts who demand reliability without the premium price tag. Featuring a 4150V Chrome Moly Vanadium steel barrel with a Nitride finish, this upper receiver offers superior corrosion resistance and enhanced surface hardness for a longer-lasting lifespan.
Key Performance Features:
- Precision Barrel: The 10.5″ barrel is chambered in 5.56 NATO with a 1:7 twist rate, making it ideal for stabilizing a wide range of bullet weights, specifically heavier 62gr and 77gr projectiles.
- Nitride Treatment: Unlike traditional chrome lining, the Melonite/Nitride finish treats the metal itself, providing excellent accuracy and a smoother surface for easier cleaning.
- Mil-Spec Quality: The forged 7075-T6 aluminum upper is hard-coat anodized to MIL-SPEC standards, ensuring a perfect fit with any standard AR-15 lower receiver.
- Reliable Gas System: Equipped with a carbine-length gas system and an F-marked front sight base for consistent cycling and a classic profile.
Note: This is a stripped assembly and does not include the Bolt Carrier Group (BCG) or Charging Handle.
