Both the XMR-8 and XMR-8/B utilise Phade Technology Industry's Internal Non-Expelling Radial Inverse Action (INERTIAtm) operating system. The INERTIAtm uses a 8.4mm diameter motor to power a rotating bolt lug, pushing foreward or pulling backward on a special lug on the carrier. An extremely efficient action, it foregoes the use of Recoil, direct gas impingement, or short-stroke pistons to power the automatic nature of the gun. It requires only .02 grams of lubricant to keep the motor moving smoothly. The power it expells is non-constant, using only .000453 volts, making it exprememly useful in space, as the force is not reliant on gravity. Lubricant only needs to be replaced every 45,000 rounds, and the lube itself has a shelf life of 19 years. PTI has developed 34 different versions of the X-INERTIA before they perfected the micro-amount of volts to move the bolt.
