Guns JP Enterprises: VMOS Variable Mass Operating System Industry News November 25, 2016 Join the Conversation Hugo, MN based JP Enterprises recently told us about VMOS, the Variable Mass Operating System. They apparently plan to have it available in 2017. Here’s what they want you to know about it. JP Enterprises: VMOS Variable Mass Operating System JP Enterprises introduces their Variable Mass Operating System (VMOS) enabling mass tunability and improved buffering of AR rifles. Operating systems can be easily tuned for a much wider range of applications such as suppressed rifles or exotic calibers. “There's no such thing as “one size fits all” in AR operating systems,” states JP founder John Paul. “Tuning your rifle is the only way to realize its potential and provide the performance you want. That's why we pioneered the adjustable gas block concept more than two decades ago. Tuning can be the difference between reliable function and reliable frustration.” Suppressed rifles or exotic calibers can experience excess gas and higher fouling that can easily push AR rifles outside their operational window. Using the same weights as JP’s Silent Captured Springs, the Variable Mass Operating System (VMOS) enables mass tunability and improved buffering capacity. The VMOS provides additional reciprocating mass that ensures reliable function in even difficult-to-run rifles. Like JP’s other carriers, the VMOS models feature a 100% increase in bearing surface for smoother operation, improved alignment and lower wear. The longer cocking pad also contributes to optimal reliability. Exterior bearing surfaces are polished before the carrier then undergoes a state-of-the-art, multi-vendor QPQ (Quench-Polish-Quench) process. The final result is a rock-hard surface with remarkable natural lubricity for a ball bearing smooth function with proper lubrication. The VMOS is currently available for large frame (.308) AR-type rifles starting at $319.95. Expect to see a small frame (.223) version early in 2017. About JP Enterprises in the words of the president, John Paul. Like you, I'm an avid recreational and competitive shooter. The American tradition is an endangered culture now, but that's how my father taught me and how I've taught my sons—to ride, shoot straight and speak the truth. My first gun was the requisite Daisy Red Ryder with one of my mother's old belts as a sling. I've long since worn it out but I still have it. I guess some people just never grow up. Now I've been shooting in competitions of one sort or another for nearly 40 years and my products and services are the direct result of that experience. I'm sure you've seen all sorts of firearms products that do not perform as expected, primarily because many are designed by people who are desk jockeys, not real shooters. I put on thousands of miles every year traveling to national level competitions, actually putting our products to the test. I am constantly trying to improve our existing products and services and create innovative new ideas to fill the needs of serious and recreational shooters. I also have a rather old fashioned idea about “customer satisfaction.” You'll notice that we don't have any fancy fine print guarantees with our products. My policy is simple: if you're not happy, I'm not happy. I only guarantee one thing, your satisfaction. Ask one of our customers. They're our best salespeople. Good Shooting!
