PSC-12 Upper Receiver Assembly
   Low Mass Bolt Carrier
   Armalite/Knights Pattern

As with our PSC-11 Upper Receiver Kits, we decided to release a .308 compatible PSC-12 Upper Receiver Kit to the home builder. This kit includes:

  • PSC-12™ upper receiver
  • Ejection port cover and hardware
  • Forward assist and hardware
  • Top- and side-charging systems
  • Low Mass JP Bolt Carrier
  • JP EnhancedBolt™ group (bolt, cam pin, firing pin and firing pin retaining pin)

This kit assembles exactly like a traditional .308 upper with the simple addition of the side-charge handle, which slips into place as easily as a standard T-handle. If you can build an upper, you can build your own PSC-12 and tap the potential yourself.

Compatibility: The PSC-12™ upper receiver is available in two versions for different platforms. This Armatlie version is compatible with any lower receiver that will accept a Armalite-style upper receiver such as the Knights Armament, Larue and MEGA .308 platforms. We also offer a DPMS version that will function similarly for DPMS-pattern lowers. Refer to the photos in the gallery above.

JP cannot guarantee function with any specific lower (other than our own). It is the end user's responsibility to verify final compatibility.

Notice on Fitment

While we can ensure fitment on matched receiver sets, slight variations in manufacturing tolerances, metal finishing and coatings make final fitment between one of our upper receivers and your own impossible to guarantee.

Made in the USA
