2. Inline percussion muzzleloader
The modern inline muzzleloader looks like most modern firearms. Some are equipped with a safety, and even a telescopic sight can be attached to certain models. Some inline muzzleloaders are also equipped with an electronic ignition, where a tiny spark is produced in the breech, and ignites the gunpowder more rapidly than a percussion cap would.
The inline and caplock muzzleloaders differ on where the nipple is attached. In an inline muzzleloader, the cap is in-line with the hammer and the barrel. The inline has the nipple attached to the barrel at the breech and accessed by a bolt or break action. Also, the inline model has a removable breech plug, to facilitate cleaning.

Apart from the basic parts listed earlier, the firing mechanism contains the following parts.
Nipple
The nipple is a small metal tube that is tapered and screws into the breech plug. The percussion cap is pushed onto the nipple and is held on by tension.

Hammer
The hammer strikes the percussion cap, producing a spark.
