PSA JAKL-10 .308 Upper w/ F5 Mfg Side Folding Buffer Tube Adapter – Compact .308 Power with Captured Recoil
****MUST SHIP TO FFL****
Introducing the long-awaited PSA JAKL-10 Upper in .308 Winchester, now available from F5 Mfg and enhanced with the F5 Mfg Side Folding Buffer Tube Adapter, eliminating the need for a traditional buffer tube and reducing overall length. Built around a 6061 monolithic rifle-length upper receiver, this platform is fully compatible with the PSA PA-10 Gen 3 lower and features a fully contained captured recoil system for superior handling in confined and tactical environments.
For shooters seeking extreme compactness and rapid deployment capability, this upper pairs seamlessly with upgrades like the F5 Mfg PDW Stock or F5 Mfg JAKL Wide Body Collapsible Brace, giving users maximum adaptability without sacrificing rigidity. For additional modularity and folding function, the F5 Mfg SA Adapter provides alternative stock/bracing configuration options.
Integrated Captured Recoil System – No Buffer Tube Required
The JAKL platform houses the entire recoil system inside the upper receiver. When combined with the F5 Mfg Side Folding Buffer Tube Adapter, users gain the ability to deploy a folding configuration and drastically reduce transport length without compromising performance.
Tool-Free Gas Management & Ambidextrous Charging
A standout feature is the toolless 8-position adjustable gas block, allowing quick adjustments for suppressed or unsuppressed operation. The ambidextrous knurled side charging handle shifts easily to either side without tools, providing versatility for both left- and right-handed shooters.
