The LWRC IC PSD AR Pistol in 5.56mm offers a high-performance, compact weapons platform designed for maneuverability and rapid deployment. Integrating LWRC’s patented short-stroke gas piston operating system with an adjustable gas block, this pistol configuration mitigates fouling and heat transfer to the receiver, enhancing reliability and reducing maintenance requirements compared to direct impingement systems.
Key Features
LWRC Short-Stroke Gas Piston System
This system ensures cleaner, cooler, and more reliable operation. It redirects gas pressure to cycle the action via a short-stroke piston, isolating hot gases and carbon from the bolt carrier group. This design reduces wear on critical components and maintains consistent performance in adverse conditions, further optimized by an adjustable gas block for varied ammunition or suppressed use.
Monoforge Upper Receiver
The IC PSD features a monolithic upper receiver machined from a single block of aerospace-grade aluminum. This construction method eliminates potential flex points between the receiver and handguard, providing a rigid platform for optics and accessories, and maintaining consistent zero under strenuous use.
Cold Hammer-Forged NiCorr Treated Barrel
The 8-inch barrel is cold hammer-forged from 41V50 chrome-moly-vanadium steel and treated with LWRC’s proprietary NiCorr process. This treatment enhances corrosion resistance, heat dissipation, and extends barrel life beyond traditional chrome lining, while preserving bore accuracy for repeatable performance.
Ambidextrous Controls
Designed for operational efficiency, the IC PSD includes fully ambidextrous fire selector, magazine release, and bolt catch. This facilitates seamless manipulation for both left and right-handed operators, and maintains weapon control during dynamic engagements.
Proprietary Rail System
A robust, free-floating LWRC proprietary rail system integrates directly with the monolithic upper receiver, providing a secure and stable platform for mission-essential accessories without compromising barrel harmonics or accuracy.
