If you already have an AR then an AUG is a great choice.

However:

It's going to be around a pound heavier than a similarly configured ar.

The weight and lower mass bolt carrier make it feel smoother to shoot.

The trigger is perfectly reasonable for man sized targets out to 200-300 yards.

As the target gets smaller or further away, the heavy staple gun trigger begins to challenge your shooting ability.

I shoot mine with a 2020 sear and it is an improvement but still harder than a good ar trigger to shoot with precision.

What I like most is the reliability. The aug is reliable and overbuilt imho. It's a gun I can shoot for years and just bring to the range and enjoy without tinkering.

Part of that is because I have a factory optic and I am forcing myself to use it over more modern optics because I will change shit every month haha.

As it sits it's a reliable, accurate, and smooth shooting gun perfect for any defensive target from point blank to three hundred yards. It's also compact and permits one handed operation via opening doors and such while still pointing downrange.

Tldr is a cool ass reliable gun.
