Overview
The Palmetto State Armory 10.5" complete upper provides an accessible entry point for compact AR-15 configurations without breaking the bank. PSA has built a reputation for delivering functional, reliable firearms at value-oriented price points, and this upper exemplifies that philosophy. The 10.5" barrel length is highly maneuverable while still providing reasonable ballistic performance for close-quarters applications.
The 4150V Chrome Moly Vanadium steel barrel features a nitride treatment that provides excellent accuracy, durability, and corrosion resistance. While not as robust as chrome lining, nitride treatment offers comparable performance for most civilian applications at a lower cost. The 1:7 twist rate ensures compatibility with heavier 5.56 ammunition, and the carbine-length gas system provides reliable cycling.
The forged 7075 T6 aluminum upper receiver features M4 barrel extension and feed ramps for enhanced reliability. A low-profile gas block sits under PSA's 9" Lightweight M-LOK free-float rail, and an A2 flash hider caps the 1/2x28 muzzle. The upper ships without a bolt carrier group or charging handle, so budget for both. This upper represents an excellent value for budget-conscious builders, first-time AR owners, or those building a secondary platform for training or range use.
