I am not that well versed as to what causes the high rate of failures on ar’s which is why spec ops was begging jsoc back in the early 2000’s to allow them to use ak’s. As the type of ops they do they can afford to be screwing around with jams and from what I have heard a little sand will stop an ar just like the many Vietnam vets stories about failures in the jungle due to dirt and/or moisture. Which is why I have alway gone with aks as they are accurate enough and the African militias in the bush keep them running with old motor oil and stuff. Someone once said the di gas system is part of why ar’s fail, which I know a big part is the tight tolerances versus the Ak which is loose as hell(like my ex wife😂) compared to the ar. But, I want to provide my kids with a gun that I can put optics that will hold a zero, lights and an an/peq as I have plenty of 3+ fast helmets with shrouds and I am working on a second set of nv. Which due to pricing I am wondering if those day/night nv scopes are a better route as they as so much cheaper and I don’t know how fast the green tubes degrade over time as I figure it might be 15-30 years before the bottom falls out and things get real ugly all around the world but real bad here as we are a heavily armed country. Where most 3rd world countries and Europe is it only the hard core criminals that have guns. I am just trying to set my kids up as best as possible with a good “insurance” policy. Thanks for all the help
