Ehhh, you'd be surprised how far you can get out there with such crude sights. I've surprised myself with a friend's AUG A1 with the nubs. Managed to ring a 100 yard 24" gong multiple times in the first magazine. Probably could have stretched it to 200 yards but no such thing was available.
Although I'd stress that was due to marksmanship, a perishable skill, that enabled me to do that. You aren't gonna be having an infantryman practice with crude sights or hinder himself purposefully in training to practice the principle of marksmanship. You are gonna have him qual'd on the optic on what, a yearly or monthly basis? The rest is mundane shit from cutting grass with hand scissors to mopping up the driveway when it's raining.
