Absolutely. I've tried them all over the years but for most of what you'll need that one fits the bill.I think a 50 / 200 yard zero makes much more sense because you never know when you have to might make a quick shot at 35, 50, 75, 100 or 150 yards, and you should not have to remember how many *feet* low to aim.
I'll assume his indoor range is longer than just 10 yards. Perhaps 25 yards long? That's what my indoor range is. Did he never shoot at 25 yards indoor and notice he was "slightly" high? He didn't have to go outside to figure that out. So did he re-zero the gun to a more realistic range?The other day I shot an AR15 carbine with a red dot optic mounted a few inches above the flat top receiver. The owner of this gun shoots almost exclusively at indoor ranges, so he's sighted it in at something like 10 yards to be dead on.
We shot it outdoors, and found it was quite a bit high of 25 yards but it was off the paper & even off the backstop 8 feet above the point of aim at 100 yards!!
You are right on the money.At 25 yards you need to zero 1.5 to 2 inches low on the center depending on the ammo.
So that they might actually be able to reasonably hit their target at longer range if necessary?But most self-defense shootings take place at less than 10 yards anyway, so why would somebody intentionally zero their weapon for 25 or 50 or 100?
I believe that's his line of thinking.
