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.

HEX–Inline percussion muzzleloader

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.
