PSA JAKL 14.5″ Rifle Length Upper Assembly 5.56NATO w/Knurled CH/BCG Rugged Flash Hider

Elevate your AR-15 build with the PSA JAKL 14.5″ Rifle Length Upper Assembly in 5.56 NATO — the ultimate hybrid piston-driven upper from Palmetto State Armory. This innovative long-stroke gas piston system combines AK reliability with AR-15 modularity, delivering smoother operation, reduced recoil, and exceptional durability for range, duty, or defensive use.

Built around a rugged monolithic 6105 rifle-length upper receiver, the PSA JAKL upper is fully compatible with any standard Mil-Spec AR-15 lower receiver (requires a PSA JAKL-specific buffer system for proper function and to prevent damage). The fully captured buffer system in the upper shortens overall firearm length and enables side-folding stock configurations for compact storage and transport — perfect as a truck gun or SHTF rifle upgrade.

Key features include an ambidextrous side charging handle (adjustable without tools), a toolless 8-position adjustable gas block for suppressor use or tuning, and easy field stripping with no tools needed for the carrier, recoil assembly, and sled. The premium Rugged Suppressors JAKL R3 Flash Mitigation System (pin & welded) provides superior flash reduction, zero muzzle ring, and snag-free design while remaining over 30% lighter and 26% shorter than competing 5.56 options — suppressor-ready for rifle and multi-caliber cans.
