Abstract: An ammunition system and associated ammunition for firearms, particularly for muzzleloader firearms, having a predetermined amount of propellant charge housed in a casing, and a separate projectile having a sabot. The casing has a cap sealing the casing muzzle end such that the cap and the sabot provide seals to trap propellant gases within the barrel behind the projectile upon firing. The cap top end and sabot bottom end interlock in mechanical communication with one another upon firing allowing the projectile exiting the barrel muzzle end to be responsive to the barrel rifling. The barrel breech end has a chamber bushing for receiving the casing and a tapered muzzle end to prohibit the projectile from entering the casing.

Abstract: A muzzleloader firearm is converted into a firearm adapted for firing an arrow. The stock assembly of the muzzleloader firearm is retained while the barrel assembly is completely removed, and replaced by an arrow barrel assembly. The arrow barrel assembly has a stock assembly attachment for releasably engaging the stock assembly of the muzzleloader firearm, and a barrel attachment for engaging an inner barrel tube that holds an arrow shaft with a hollow interior and propels the arrow out of the firearm when a blank cap is activated, and an outer shroud to protect the inner barrel tube and enclose a loaded arrow. The arrow barrel assembly rearward end has formed recesses for receiving the blank cap and aligning the rim of the blank cap with the firing pin of the muzzleloader stock assembly.

Abstract: An inline hammerless percussion firing system for muzzleloader firearms with a striker having a firing pin and a striker spring to linearly drive the firing pin forward. A cocking button compresses the striker spring. A pivoting retainer acts against a nut connected to the cocking button to hold the cocking button forward and keep the striker spring compressed. A sear acts to prevent the striker from moving forward until released by a two piece trigger system in which a trigger and trigger edge pivot relative to each other with lost motion before releasing the sear, allowing the trigger edge to move out from below a safety notch in the sear, where firing is prevented, to below a firing notch in the sear to prevent accidental discharges from impact. The cocking button can be released by an uncocking button. Releasing a barrel catch resets firearm to the initial safe position.
