Just to comment on Infra_man99's post on the Steyr AUG based on my own experience with it, during my time in the Australian army.
Most modern western rifles have problems functioning in sandy and muddy conditions due to their tight tolerances in moving parts, diligent maintenance is required regardless of whether the rifle is of bullpulp configuration or not.It has problems functioning in sandy or muddy conditions.
I don't see how the safety catch can be fragile when it's just a plastic block that slides sideways and stops the trigger when on safe.Its safety switch is fragile.
I do not know that trigger feedback means, when taking deliberate, aimed shots, I just align the rifle with the target, apply a constant pressure on the trigger until the weapon fires, when volume is required, I just snatch the trigger. As to the long trigger pull, AUG does not have fire selector, pull the trigger halfway for single shots, pull it all the way back for full auto.Its trigger lacks good feedback and it has long pull.
It doesn't have a hand guard that encloses large part of the barrel like other rifles, I don't believe this is due to the bullpup configuration, as all other bullpup rifles do have proper hand guards. Plus, you meant to hold the Steyr by the fore grip, which keeps your hand much further away from the barrel that other rifles.Its barrel and construction lacks sufficient protection to protect the shooter's face and hands from the rifle's heat.
How can one judge whether the ejection port of a rifle can be weak or strong?Its ejection port was fragile, and this is really bad since the bullets are ejected close to the face.
When was the last time a round exploded inside an AUG?If the gun ever has an explosion at its ejection port, the gun will have a good chance of permanently damaging the shooter's face or eyes.
You should give your weapon a lot of maintenance regardless of its design and construction, when in the field, you should clean and lubricate your weapon every morning and after every firing even if you are using an AK-47.To decrease the probability of these problems, the shooter is told to give the Steyr Aug lots of maintenance.
Apart from reloading, as it is hard to change the magazine without taking the weapon off the shoulder, the rest are just personal preferences, and a military weapon that everyone finds comfortable does not exist.Some shooters even said the Steyr Aug is uncomfortable to use: the gun's handle and grips are unnatural, reloading is difficult, and the balance is bad.
