PSC-19™ Upper Receiver Assembly

   Large Frame | DPMS

As with our PSC-11™ Upper Receiver Kits, we decided to release a .308 compatible PSC-19™ Upper Receiver Kit to the home builder. This kit includes:

  • PSC-19™ upper receiver
  • Ejection port cover and hardware
  • Forward assist and hardware
  • Choice of top- and side-charging handles:
    1. Top charge: Standard or Radian Raptor-LT
    2. Side charge: Low Profile or Competition
  • Choice of JP bolt carrier:
    1. Full Mass Operating System (FMOS™) JPBC-5
    2. Black Low Mass Operating System (LMOS™) JPBC-4
    3. Polished Stainless Low Mass Operating System (LMOS™) JPBC-4SP
    4. Standard Steel Variable Mass Operating System (VMOS™) JPBC-7
    5. Heavy Steel Variable Mass Operating System (VMOS™) JPBC-7H2
    6. Aluminum Variable Mass Operating System (VMOS™) JPBC-8
  • JP High Pressure 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-19™ and tap the potential yourself.

Thermo-Fit™ Barrel Installation

The PSC-19™ was deliberately manufactured with a precise undersized barrel extension bore, requiring use of our proprietary Thermo-Fit™ barrel installation process. Installed this way, the barrel attains a virtually unbreakable heat meld to the receiver, vastly increasing the accuracy and precision of the rifle.

You can view our video on the Thermo-Fit™ installation here.

Compatibility and Fitment

The PSC-19™ upper receiver is compatible with any lower receiver that will accept a DPMS LR-308 upper receiver. We also offer an Armalite version that will function similarly for Armalite-pattern lowers like Knights Armament, Larue and MEGA .308 platforms. Refer to the photos in the gallery with particular attention to the contour on the rear of the receiver.

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