Let’s get you through the expert’s overviews on the budget scope options for your AR-15 Riffle under a hundred bucks: 

How Many Rounds Can An AR 15 Fire In A Minute?

It depends on many things. If you are a beginner, you may fire 10-15 rounds with your AR 15 in a minute. Since AR 15 is a semi-automated rifle, you need to pull the trigger every time you want to fire. Also, you need to let the trigger go forward to be ready for the next shot. Besides, if you need to target something, you can fire less for sure.

Moreover, if the magazine is finished, you have to reload it again. So as you can see, there are a lot of factors. But with a little bit of practice, you can empty a 30-round magazine within 10–12 seconds. If you use good AR-15 rifle scopes, they’ll help you get better accuracy if you’re shooting at a target with your AR-15 rifle. 

What Scope Does The Military Use On AR 15?

Usually, the military uses good AR-15 optics from red dot sights to multi-level zoom scopes. That’s because its lightweight construction helps in fast movement and quick target acquisition. And it’s often used for competitive shoot-down, self-defense, as well as predator hunting.

How Far Can An AR 15 Rifle Shoot?

Bullets from the AR 15 rifle can reach up to 500 yards of distance when shot. But it will lose its energy and lethality. Because at 500 yards, the AR 15 rifle bullet’s lethality will be equivalent to a handgun bullet.
