Turn the lights off in your house, grab your M1 Garand, and try and see a target in the room.
Then try it with either night vision or a light.
Come back and tell us the results.
Literally no one in 2022 who actually uses these guns uses them with zero accessories. This isn't WW2, or WW1, or Korea. And if you asked those guys back then whether they wanted the ability to see and shoot targets either in the dark or further away, they'd all probably say yes.

This is what guns look like in the modern day. Optics. Silencer. Rails. Collapsible stock. Lights.
If you're dead serious that adding a light and an optic to a rifle is "messing with something that works fine", thus "begging for problems", then I want you to go tell that to everyone taking Ridgeline's night classes this year. Go there and tell us how that works out for you.
