We are constantly reevaluating our products from both the safety and reliability standpoint, and it has come to our attention that the thread locker product used to secure the button-head screws in the JP Anti-Walk Pins installed in JP assembled rifles and lowers may not be properly curing. This could allow the retaining screws to vibrate out of the pins during live fi...
JP LRP-07™ rifles chambered in 7.62x51 are designed to function with SAAMI spec. commercial-grade factory .308 Winchester ammunition. We recognize that many avid shooters reload for their rifles, and carefully assembled hand loads should function when appropriate component combinations are used and brass is properly sized and gauged. However, we will not warrantee damage caused by hand-loaded ammunition that is not compatible with the rifle.
We do not recommend the use of surplus military ammunition due to the considerable variation from manufacturer to manufacturer, lot to lot, year to year, and from the components used and the processes in manufacturing. In some cases, surplus ammo has been mass tumbled to clean the years of tarnish off the cases, which actually causes the powder to break down. This drastically changes the burn rate of the propellant and the subsequent internal ballistic characteristics of the load, leading to the potential for extreme pressures.
