It all depends on the model your looking at. So, to make it simple, elaborate. My pump action M56A uses airsoft shotgun shells, that act as magazines. So in a real shotgun, when the shell of a shotgun is fired, the Shell ejects, and the bb's fire. In an airsoft shotgun, depending upon the model, a shell shotgun fires 1 or 3 bb's, and without ejecting the shell, you pump again, causing more pre-loaded bb's into the chamber. But in some Airsoft shotguns, they use Magazines. You insert the magazine into the underside of the gun, and when you re-pump, bb(s) load into the chamber. That would be the logical answer. You used the word "Have". Do i "have to use shells". There are magazine alternatives, and you can always do it the good old fashion manual loading method. You could "screw" the loading mechanism, and manually force the bb's into the chamber. Not recommended. Any more questions, email me.
no, just buy more clips
Your gun needs to visit a gunsmith, It may be dirty, or simply have parts worn or broken. The chamber is what the shell is fired from. You load shells into the magazine.
Remove magazine, load cartridges into magazine, replace magazine, operate slide to chamber cartridge.
Load, chamber, engage firing mechanism
That depends on what you mean by "real guns". If you are asking "Can an airsoft gun load, chamber, and cycle a live firearm cartridge?", the answer is no. If you are asking "Does my state consider an airsoft replica a firearm?", the answer is "Maybe". Depending on where you live, airsoft replicas may be classified as firearms. The best place to start looking is to search for the definition of firearm in your state codes. If all else fails, you may be able to get suggestions for which sections of your local criminal codes cover airsoft replicas by contacting NON-EMERGENCY dispatch for your local law enforcement agency. If you are asking "Should I treat my airsoft replica like a firearm?", the answer is yes. All firearm safety rules should be followed with anything that launches a projectile, especially when it looks like a real gun.
Depending on load, bbl length, and conditions 10-100 meters.
First you have to find the right sized bb's for it and then load it into the cartridge and then cock it... point... and pull the trigger
The Marine Corps does not have an official or specific definition of "lock and load." However, in general military terminology, "lock and load" is a command given to prepare a weapon for firing by loading it and setting it to the ready position. It typically involves placing a round into the chamber of the firearm and ensuring it is ready for immediate use.
You need a gunsmith.
3, including the one in the chamber.
The safety is just to not load the chamber until you're ready to fire it.
