Muzzleloader systems including a pre-packaged propellant charge with a primer and receptacle. The muzzleloader system may include a propellant containment vessel separate from the primer and the projectile and that doesn't contact with the projectile until assembly. The muzzleloader may be rear loading, with a constriction portion forward of the breech chamber. The propellant containment vessel may include a body portion having a forward opening, with a propellant charge disposed therein and a cap portion that is crimp rolled within the mouth of the vessel to seal the forward opening. The closed end of the propellant containment vessel may define a primer receptacle configured to receive the primer. The receptacle may define a depth that is less than the primer height so that, when inserted into the receptacle, the primer extends rearwardly beyond the containment vessel. The muzzleloader system may be configured to fire only specifically configured propellant containment vessels.

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 firearm has a lower receiver with a first channel formed in a first surface of the lower receiver, and an upper receiver attached to the lower receiver at a pivot point. A compressible material is disposed within the first channel between the upper receiver and lower receiver. The upper receiver compresses the compressible material when the upper receiver closes onto the lower receiver. A recess can be formed within the first channel and extends into the lower receiver deeper than the first channel. A second channel is formed in a second surface of the lower receiver. Alternatively, the lower receiver has a slot formed in a surface of the lower receiver, and the compressible material is disposed within the slot. The slot includes a bottom surface and vertical surface extending from the bottom surface to the surface of the lower receiver, and rounded ends.

Provided is a fast cycling/low recoil pistol caliber carbine assembly. The carbine assembly may include an upper receiver, a lower receiver, a feed ramp, a bolt stop, a magazine, a control mechanism comprising a control lever, a control base, a control pivot pin, and a control spring, an ejector, a gap filler member. The assembly provides last round bolt hold open, trigger finger actuated bolt release, short stroke cycle, barrel ramp, ambidextrous magazine release, and uses Glock magazines.
