PSC-21™ Upper Receiver Assembly
Ever since we debuted our dual-charge system at SHOT Show 2011, it's been a hit. Keeping with our new receiver styling, the PSC-21™ is the newest iteration of our small-frame dual-charge upper compatible with any Mil-spec pattern lower. This design integrates the popular side-charge system of the LRI-20™ and SCI-20™ platforms into a machined-from-billet receiver that doesn't sacrifice any of the functionality or compatibility of a standard Mil-spec upper. This makes the PSC-21™ a best-of-both-worlds option for any application: action shooting, precision rifle, hunting or duty/defense.
This upper receiver kit brings the PSC-21™ to the home builder and includes:
This kit assembles like a standard forged 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-21™ and tap the potential yourself.
Note: The PSC-21™ is compatible with any lower receiver that will accept a standard Mil-spec upper receiver, but JP cannot guarantee function with any specific lower (other than our own). It is the end user's responsibility to verify final compatibility.
Thermo-Fit™ Barrel Installation
The PSC-21™ 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.
