PSA JAKL (14.5") Complete Upper Receiver CALIFORNIA LEGAL - .223/5.56 - Smoke

PSA JAKL Pistol Kits are now available!

This platform is built around a 6105 monolithic 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.

Upper: 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 4-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.

Lower Build Kit: In this kit, you will find everything you need to convert your AR-15 Mil-Spec lower into a PSA JAKL Pistol Lower. Featuring a Classic A2 grip and our enhanced polished trigger (EPT) which helps reduce pull weight, and is built to last. Also included are the JAKL stock adapter assembly & JAKL proprietary bolt catch that are required for your lower to function with our PSA JAKL upper assemblies. 

*The included Blue Loctite® must be used for the threaded adapter and adapter screw to avoid backing out during the use of the firearm. 

Comes with proprietary JAKL bolt catch that must be installed on the lower for proper function

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.
