Found this recently. Definitely worth a side-by-side with Vaidya’s Evolution of the War Rifle. What’s next? Is it still going to be an actual weapons system? Or is the military-developed model going away? Real weapons technology innovation may still come from DARPA; it will just be GPS or the internet this time around.

Awesome
The evolution of the war rifle has some mistakes in it. The alleged M1 Garand is actually an SKS. the ACR should be on there too, forget the SCAR.
