AimpointPRO. Twenty pack of lithium batteries. Follow the instructions and keep it set at the correct brightness setting to maximize battery life and adjust for visibility. More than likely, your grandkids will be working their way through that pack of batteries you invested in while you're long in the ground.
Seriously, Aimpoint is the gold standard of red dots. $100 dollars more than what you have and you will have one of the best close-range sights ever devised which will realistically cover just about everything you need an optic for. ACOGS are nice but the only real benefit they have over an aimpoint is positive target ID at range. I used mine a few times to scope out tresspassers to decide if they were carrying fishing poles or rifles, but anything inside of 100 yards I prefer the Aimpoint.
Don't worry about batteries. I've had an H1 for three years and just changed my first set of batteries that came with the optic. Buy lots of them and forget about it. Even in an ACOG the tritium has a 12 year half-life, and that's 2.1 batteries for an Aimpoint.
