<p>PSA JAKL 9mm Uppers are now available!<br /><br />This platform is built around a 6105 monolithic upper receiver designed to be compatible with an AR-V lower receiver. The PSA JAKL offers a buffer system that is fully captured in the upper receiver, shortening the overall length of the firearm.<br /><br />The PSA 9mm JAKL features a direct blowback design with a 17-4 stainless steel bolt carrier group. 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. Field stripping and removal of the JAKL carrier, recoil assembly, and sled assembly can all be done without tools for effortless cleaning.<br /><br /><strong>Must be used with JAKL buffer system found on PSA JAKL 9MM lower or lowers built with a PSA JAKL 9MM lower build kit.  Failure to use the PSA JAKL proprietary buffer system may result in damage to the JAKL upper and lower.</strong><br /> <br /><br /><br /><br /></p>
