What is top loading gun?

A top loading gun is a type of firearm where ammunition can be loaded into the gun through a port on the top of the gun's receiver. This is in contrast to bottom loading guns, which require ammunition to be fed through a magazine or chamber at the bottom of the gun.

Top loading guns are commonly found in shotguns, as well as some rifles and pistols. They typically have a smaller capacity than bottom loading guns, as they require the user to manually load each round.

One advantage of top loading guns is that they can be easier to load and unload than bottom loading guns. The top loading design also allows for easier cleaning and maintenance of the firearm.

However, top loading guns may not be as reliable as bottom loading guns, as the gravity-fed loading system can sometimes cause jams or misfires. They may also be less popular among gun enthusiasts, as they are less common and may not offer as many customization options as bottom loading guns.
