An ammunition loading and storage assembly includes a housing and an upper cover rotatably arranged on the housing. The housing includes a plurality of discrete elongated cavities distributed in the housing along a center axis of the housing, a plurality of discrete grooves distributed on an outer surface of the housing. The upper cover includes a main body with a protruding buckle, a guide tube extending from the main body. The guide tube deviates from each of the plurality of elongated cavities for blocking the elongated cavity to prevent leakage of ammunition under the condition of the protruding buckle received in one of the plurality of discrete grooves. A straight channel is formed by the guide tube cooperatively with one of the plurality of elongated cavities under the condition of the protruding buckle detached from one of the plurality of discrete grooves.

Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end the propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end and seats against the constriction portion. The propellant containment vessel may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The containment vessel further comprises a primer mechanism that may be integrated into the proximal end of the containment vessel.

A muzzle brake for use with a firearm such as a muzzle-loading firearm, and including at least one access port in the muzzle brake that is large enough (for example at least about 0.5″ or more minimum dimension) for access by a user's fingertip to remove a cleaning patch from the muzzle brake. One or more vent ports that are relatively smaller than the access port may also be provided in the muzzle brake.

A muzzle loader AR upper receiver can include a muzzle loader AR pattern upper receiver configured to be coupled with an AR pattern lower receiver. The muzzle loader AR pattern upper receiver includes a body with a barrel opening. A muzzle loader barrel is coupled to the barrel opening of the muzzle loader AR pattern upper receiver. A muzzle loader AR rifle can include the muzzle loader AR pattern upper receiver and the AR pattern lower receiver coupled to the muzzle loader AR pattern upper receiver. A method of forming a muzzle loader rifle can include: providing a muzzle loader AR upper receiver; and coupling the muzzle loader AR upper receiver to an AR pattern lower receiver. A muzzle loader kit can include the muzzle loader AR pattern upper receiver and any other component, such as a ramrod, barrel, or AR pattern lower receiver.

A breech plug for inline muzzle loading firearms configured to use a blank powder cartridge loaded from the breech end, rather than powder loaded from the muzzle, and configured to place the projectile in substantially the same location in the barrel as if powder had been loaded from the muzzle end.

A force measuring device for a muzzle loader.
