I fired assault rifles when I was in the military.
I shot assault rifles at the shooting range.
I had to do it in three different positions - in the standing position, in the foxhole position and in the prone position.
The assault rifles were only equipped with the common traditional iron sights to help the shooters to aim at the targets and to shoot at them.
I dislike the conventional iron sights, as you always have to align the front sight with the rear sight onto the target for an accurate shot.
Whenever I have to shoot at a shooting range, I always prefer to use a sniper rifle, which is equipped with a zoom lens sniper scope that allows me to be able to see the target very clearly, even at very long range/ distances.
You can hit a lot of targets with ease with normal assault rifles with iron sights, but it is definitely much easier if you were to use sniper rifles with sniper scopes instead.
If there is a new type of rifle optics technology available for me to use, I would certainly want to take advantage of it as much as possible to help me to be able to aim much more accurately and confidently.
In other words, I always prefer to use a new high tech weapon that can dramatically increase my marksmanship skills than an old-fashioned weapon that is antiquated and unable to help me to hit my target accurately.
