Yes, it's an older gun. The lever action actually opens or "breaks" the gun in half so you can re-load a shell. It's a single shot so you have to reload every time. Not really uncommon but the top lever that you push sideways is much, much more common.
Single shot Muzzle loaders of the "old" style are an example. There is no action to be opened - all loading is done by "stuffing" powder, wading and projectile down the bore of the barrel.
opens is action verb
A door knob turns to let people open or close the door. For vehicles, a lever or button-lever opens the door. For swinging doors, body weight (pushing) opens a door.
A lever under the dash just to the left of the steering wheel. The other lever opens the hood.
Depends on what type of BB gun it is. Some have a small lever to load and chamber the next BB. When that lever is pulled back, the breech is open. Some have an action which both charges the gun and opens the breech to load another round, such as the lever action BB guns, pump action BB guns, etc. In some cases, the breech may be exposed during this time, or it may not be (such as with the Red Ryder). For BB pistols, if they're revolver types, usually the top portion is hinged and can be opened to expose the breech this way. Some are made to resemble semi automatic pistols, and pulling back on the portion of the slide which can be pulled back opens the breech.
