The PSA Gen3 PA10 .308 1:10 Nitride or Stainless Steel 15″ M-Lok Upper with BCG & CH is a high-performance, ready-to-install AR-10 upper receiver assembly from Palmetto State Armory, designed for reliability, accuracy, and versatility in long-range shooting, hunting, or tactical applications. Built on the enhanced Gen3 PA10 platform, this complete upper delivers excellent value with premium components at a budget-friendly price.
Key features include a durable 4150V Chrome Moly steel barrel with a Black Nitride or Stainless Steel finish for superior corrosion resistance, extended barrel life, and smooth operation. The 1:10 twist rate stabilizes a wide range of .308 Winchester / 7.62x51mm NATO projectiles, while the mid-length gas system provides smoother cycling, reduced recoil, and better overall reliability compared to rifle-length systems.
Paired with a low-profile 3-position click-switch adjustable gas block (allowing easy tuning for different loads, suppressors, or ammo types) and a Black Nitride or Stainless Steel gas tube that withstands high heat and corrosion. The barrel is dimpled for secure gas block installation and features an A2-style flash hider on 5/8×24 threads.
The forged 7075-T6 aluminum upper receiver is precision-machined and hardcoat anodized (MIL-8625 Type 3 Class 2) for maximum durability. It comes equipped with a 15″ PSA M-Lok free-float handguard featuring enhanced anti-slip and anti-rotation QD sling points, giving you plenty of real estate for accessories like lights, grips, bipods, or optics without adding unnecessary weight.
Reliability is boosted by a Toolcraft PA10 BCG (made with a 9310 steel bolt, extra-power extractor springs, nitride-treated carrier, and staked gas key with Grade 8 fasteners) plus a lightweight 7075-T6 aluminum charging handle.
This Gen3 upper is compatible with most DPMS-style .308 lowers (though PSA recommends matching Gen3 components for optimal fit, appearance, and performance). It’s an ideal upgrade or build foundation for anyone seeking a powerful, accurate .308 platform without breaking the bank.
What’s included:
- Complete barreled upper receiver
- Toolcraft PA10 BCG with extra power extractor spring
- 7075-T6 charging handle
- A2-style muzzle device
Perfect for hunters needing flat-shooting long-range capability, competitive shooters, or builders wanting a nitride-treated, adjustable-gas .308 upper with modern M-Lok modularity.(Note: Always check local laws for firearm purchases/shipping. Follow all safety guidelines.)
