JP RIFLES | JP EnhancedBolt™ Assembly Completion Group JPEB-223
Whether to admit it or not, the good old Mil-spec bolt has had a good run, but it's long past its retirement age, and the JP EnhancedBolt™ is there to pick up where it left off.Material matters, and the Carpenter 158 steel of the standard Mil-spec bolt is suboptimal for such a high-load application leading to a life expectancy of only about 6,000 rounds. In fact, standard bolts will start to show stress cracks on the locking lugs adjacent to the extractor cut after only 3,000 rounds while cracking at the cam pin hole and weak extractor spring tension only add to the problems of the Mil-spec bolt. Fine enough for its time, the material used in these standard bolts is simply not the best choice by today's standards.
The SAE 9310 of the JP EnhancedBolt™ is a superior steel alloy in virtually every way compared to the C-158, whether in its resistance to structural failure or life expectancy, both of which far exceeding the Mil-spec. Just as with the transmission gears for Formula 1 racers which are also made from 9310, the operational demands of a bolt assembly are ideally suited to this state-of-the-art material, with actual endurance torture tests prove it.
Beyond its material advantages, the design of the JP EnhancedBolt™ boasts many other advantages, including the addition of material around the cam pin hole to eliminate this inherent weak point of the bolt design itself. Each bolt also comes assembled with JP's proprietary Enhanced Ejector, Extractor and Gas Rings for improvements in every subcomponent. Yet even with these advanced components, the JPEB-223 EnhancedBolt is fully compatible with the readily available Mil-spec subcomponents, including a standard configuration extractor - all the benefits of a state-of-the-art proprietary platform with none of the inconvenience.
Kit includes bolt assembly, firing pin, cam pin and retainer pin. This version of the bolt is compatible with any AR-15 platform using a Mil-spec bolt carrier and sub-components.
