NVGs are not bad, your head is a better place for the weight. But having a good NVS that can be removed for day use is not bad ether. I have an PVS-4 with a Third gen replacement tube that mounts to the carry handle. It lives on my A2 mostly, but I have mounts for the M14 too.Maybe so, but certain additions do offer additional capabilities. If I was going out after dark, nvgs helped us rule the night peq15’s helped. I trained with an a2 hit the pipeline with an a4 and as soon as I hit the fleet got my m4. After years of nvg and ir usage. I wouldn’t go back. But stoner designed a great rifle for my grandfather’s generation.
The m1 was also the great implement of war ever designed… times change technology changes. Everyone has a philosophy of use that is particular to them. And judgement from outside voice can deter one from using what they see fit out of trying to fit the proper narrative on the internet.
I’m not saying you’re wrong, I just think I’d rather have my quad rail and optics as opposed to plastic hand guards and iron sights. But that is just strictly my personal opinion. Either way, quads are not my preference, m lok for me.
