F5 MFG | PDW BRACE AND LOWER, PSA JAKL UPPER | COMPLETE FIREARM

Compact. Bufferless rear profile. Monolithic reliability. Ready out of the safe.

Build a purpose-designed, short-barrel AR that blends F5 Manufacturing’s compact, bufferless PDW ergonomics and precision-machined lower with the battle-proven, piston-driven PSA JAKL 8.5″ .300 AAC Blackout upper. This complete firearm delivers a short, highly maneuverable platform ideal for close quarters, defensive use, and enthusiasts who demand a compact system without sacrificing reliability or mounting options. F5 MFG PDW JAKL Wide Body Collapsible Brace

Why this configuration matters

• True compactness: The F5 PDW brace gives the shooter a stable cheek-weld and shoulder support without requiring a rear-mounted buffer tube, preserving a slim, low-profile rear section and making the firearm easier to store, carry, and maneuver. F5 MFG

• Upper-captured system: The PSA JAKL’s monolithic design includes a captured buffer/buffer system in the upper, shortening overall length while delivering piston-driven reliability and reduced internal fouling — ideal when pairing with bufferless rear ergonomics. Palmetto State Armory

• Precision foundation: An F5 mil-spec forged lower provides exacting tolerances, durable construction, and premium finishes (Mil-A-8625 Type III hard coat anodize or Cerakote options), creating a rock-solid interface for the JAKL upper and accessories. Mil-Spec Forged Lower Receiver
