Palmetto State Armory is proud to announce the long-awaited release of the JAKL 14.5″ Rifle upper chambered in .300 AAC Blackout! This platform is built around a 6105 monolithic rifle-length upper receiver designed to be compatible with any Mil-Spec AR-15 lower receiver. The PSA JAKL offers a buffer system that is fully captured in the upper receiver, shortening the overall length of the firearm. The PSA JAKL features a long-stroke piston design with a Carpenter 158 bolt and 4340 carrier that are an AK/AR hybrid. Our side charging handle is ambidextrous, allowing the user to change positions to the left or right side of the receiver without the use of tools. Equipped with a toolless 8-position gas block, this feature offers the ability to quickly adjust your gas block by hand when needed. Field stripping and removal of the JAKL carrier, recoil assembly, and sled assembly can all be done without tools for effortless cleaning.Must be used with JAKL buffer system found on PSA JAKL lower or lowers built with a PSA JAKL lower build kit. Failure to use the PSA JAKL proprietary buffer system may result in damage to the JAKL upper and lower. 14.5″ .300 AAC Blackout without Flash Hider/Muzzle Device, Thread Pitch 5/8×24″
