they’ve been devoloping this for a very long time, the recoil was the biggest problem for over a decade. very cool gun though, the moving bolt to transfer energy was the breakthrough. Sweet gun… I wish they would have shown the barn test. They took this thing loaded with the fragmentation grenade rounds to this small barn, like shed. And just filled it with the grenade rounds… nothin left, just scraps of wood everywhere. It was insane.
