The PRO looks like Aimpoint’s M3 series, and has the same quality you expect with all their other products. It runs on a DL 1/3N battery, which provides you with something like 3 years of battery life. Now, when they talk about battery life, keep in mind this is with a fresh battery under ideal temperature and other conditions, and at setting number _.
In real life you’ll have to replace the battery more often, especially if you use it. But the point is you can turn the sight on, leave it on, and change out the battery according to what you figure out is life expectancy for your application.
Since you can leave the sight on all the time, Aimpoint has outfitted the PRO with a clear rear lens cap. The front cap is still black, but the beauty of working with the red-dot, which allows you to keep both eyes open, is that even if the front cap is shut you can still acquire a target quickly, and if necessary make surgical shots. When you have the opportunity then you can flip up the front cap and dial in the intensity level of the dot.
It has six daylight settings, one extra bright, and four for NV kit, with the correct lens coating, and will work with the 3X magnifiers. The dot is two moa, which I prefer because it’s small enough to make accurate hits at extended distances if necessary.
If you want a bigger dot turn up the brightness, make the dot flare out some, and it appears larger. For me the four moa dot is a little big for headshots at one hundred yards. Regardless of what you use, with dots it’s important to make sure the shots are going into the center of the dot when zeroing your rifle.
The PRO comes with a mount and spacer for attaching the sight to your flattop AR. For shotguns or subguns you’ll need to remove the spacer. The mount has a large knob for tightening, with a preset tension for the proper torque for securing the sight. This makes it sort of fool proof.
The best part of the new sight? The price. I’ve found it for sale for $400, which is a good deal for a great sight, with mount, and with spacer. All you have to do is install the battery, clamp it on the rifle, and zero it. Then make sure to practice so you have the proper skills to use it, especially stuff like using the sight as a rear aperture in conjunction with the front sight in case the red-dot stops working.
Good kit is necessary. Practice is mandatory. And remember, technology can never replace skill.
