Description

The PSA Gen3 PA10 .308 WIN 1:10 Stainless Steel 15″ Lightweight M-Lok Upper with BCG & CH is a high-performance, ready-to-install complete upper receiver assembly built on Palmetto State Armory’s improved Gen3 PA10 platform. Designed for reliability, accuracy, and customization, this .308 Winchester (7.62x51mm NATO) upper delivers excellent long-range potential with enhanced features for smoother operation and easier tuning.

Crafted around a premium 416R stainless steel barrel with a 1:10 twist rate and mid-length gas system, it provides superior corrosion resistance, consistent accuracy, and reduced recoil compared to shorter gas systems. The dimpled barrel profile (A2 style) accepts standard gas blocks easily, while the low-profile 3-position adjustable click-switch gas block lets you fine-tune for specific loads, suppressors, or ammunitionideal for precision shooting, hunting, or tactical applications.

Paired with a lightweight 15″ M-Lok free-float handguard featuring anti-slip and anti-rotation enhancements, plus partial Picatinny rail sections for optics and accessories, this upper offers a slim, modern profile with ample real estate for lights, grips, lasers, and more. The forged 7075-T6 aluminum upper receiver is precision-machined and hardcoat anodized (MIL-8625 Type 3 Class 2) for maximum durability and a premium black finish.

Included is a reliable Toolcraft PA10 BCG with nitride-treated 9310 steel bolt, 8620 carrier, properly staked gas key (grade 8 fasteners), and extra-power extractor spring for consistent extraction and longevity under heavy use. A 7075-T6 charging handle rounds out the package for smooth, dependable operation right out of the box.

Key advantages include:

Mid-length or Rifle-length gas system for softer recoil and extended parts life

Adjustable gas block for optimized performance

Muzzle threaded 5/8-24 with A2-style flash hider
