Israel about to replace the M4. ..Not saying the M4 is bad, but the new rifle best fits THEIR needs. Besides, it is a "home grown" weapon, and I am sure it will work well for them.
https://www.youtube.com/watch?v=mDh8JiT4uw4 I'm rather old-fashioned I guess, but the new Mattels and bull-pups are not for me ! ..But today's troops seem to adapt to the black rifles just fine.
I like a real conventional rifle, but part of that was my era in the military. I started with the M1 Garand with KD targets out to 500 yards, later went to M14 with "sneaky Petes" out to 550 meters (601 yards).
Firing was done with Iron sights, but I still managed to fire expert.. Perhaps why I tend to think the M14 is the best battle rifle ever.
I can't imagine trying to "fix bayonet" on a new bullpup..
