JP Enterprises’ MR-19 is Big on Ergos and Small on Paper

- Rob Curtis

John Paul of JP Enterprises makes no bones about it. Within two seconds of our interview about the origins f e company’s MR-19 rifle, J.P. Is fire about traditional, drop bolt gun ergonomics.

“Gas gun ergonomics are far superior op-comb bolt gun ergonomics,” he’s talking about the trouble he almost 20 years ago finding a rifle p that’d work well in endurance, team sniper competition. That his obsession at the time. He means events in the early 2000s that were the forerunners of events current comps like Competition Dynamic’s Sniper Adventure Challenge and G3 Dynamic’s Mammoth Sniper Challenge. He was looking for something light, rigid, and most of all, ergonomic.

At the time, the Accuracy International Chassis System was the only game in town for the 700, J.P. laments.

“Ergonomically, I couldn’t stand it,” he says. “I was coming from a 3-gun background to begin with. I don’t care what I did to adjust that stock, I couldn’t get comfortable with it.” This desire to bring gas gun ergonomics to his bolt guns was the impetus for his company’s first chassis system.

The original JP chassis was the AMCS. The JP Enterprises Advanced Modular Chassis System was released in 2006. With its AR-style pistol grip and adjustable comb, it was among the first bolt gun chassis to incorporate gas gun ergonomics. J.P. wanted to get the AMCS concept to market, so he says he didn’t tackle the engineering problems associated with making his own adjustable stock when Magpul’s PRS stock would do just fine. The chassis gained a following and, as it aged gracefully, long-range precision shooting enjoyed a renascence beginning around 2010. Long-range precision competition bloomed into what J.P. calls the PRS movement as the Precision Rifle Series hit its stride around 2015.
