What kind of gun is sg sr smg ar?

Sg is a shotgun. Sr is a sniper rifle. Smg is a submachine gun. Ar is an automatic rifle or an assault rifle.

First, SG: shotgun, shot means shooting. As we all know, shotguns have no rifling, while previous guns have no rifling. Therefore, it may be because the sprayer has no rifling, which leads to the split between the shotgun and rilfegun.

Then rifling faction occupied the mainstream, and there were many subdivisions. Now muskets are basically stuck with sprayers. Shotguns and rifles are rifling.

Second, Sr: sniper rifle, sniper rifle, with high precision and good air tightness. Bullets are generally full-power rifle bullets or above, equipped with sights, mostly single-shot or semi-automatic.

Third, SMG:Sub machine gun, submachine gun, which is defined by Americans, means small machine gun, submachine gun. China's definition is quite different from that of the west. For example, standard assault rifles, such as Guan 56 Chong, are also called submachine guns.

4.AR: automatic rifle or assault rifle, both of which can be called, but there are still some differences. Automatic rifles cover a wider range of fields and are defined by form rather than scene.
