Looks like a bit of re-inventing the wheel. From what I can see looks like a slightly less hi-tech (cheaper) version of the xm301. I know there was a bit of engineering twiddling on s compact 3 barrel 25mm as well, a lot lighter but similar rpm as the 4 barrel hack in the F-35 (but again, it was cheaper to mod the current GAU-12 than build around xm301 tech). The GAST 25mm looked interesting and even made it to prototype, fast, light and reliable. Would have been nice to see the tech behind the xm301 morph into lightweight 12.7mm, 25x137mm and 30x173mm variants.
