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. An insert may be fitted within the muzzle brake to enhance wear resistance and extend its service life.

A hybrid composite and steel rifle barrel assembly relating to bolt action rifles or other firearms, including those that fire rimfire or centerfire ammunition. The inner barrel construction consists of a pre-machined and rifled steel barrel that has been machined down from its original geometry to a much lighter and smaller geometry to achieve a significant weight savings. The metal portion of the barrel that is removed, is replaced by a composite tubular structure, that slips over the machined down steel barrel which is then adhesively bonded to the steel barrel. The composite barrel consists of a plurality of concentric composite material layers including carbon fiber-based uni-directional prepreg and a unique metallic weave that is placed within the composite structure to aid in the thermal transfer of heat extending from the chamber to the muzzle end of the rifle barrel. The metallic weave is positioned so that it is the first layer(s) within the composite structure that make direct contact with the steel barrel. This metallic weave is a continuous weave that extends the full length of the barrel and not only provides a highly thermally conductive layer, but also provides significant longitudinal barrel stiffness. The resin matrix system within the composite structure is a standard epoxy resin that preferably does not contain any type of thermally conductive particulate or filler, to achieve an effective thermal transfer layer. The resulting hybrid composite/steel barrel achieves significant weight reduction compared to an all-steel barrel in addition to increased accuracy. In addition to the weight reduction and accuracy benefits associated with this invention, is that the movement of a bullet associated with shooting through a cold barrel (cold bore) versus a hot barrel is reduced substantially.
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.
Improved firearms including one or more of a removable and/or interchangeable top cover, an improved extractor mechanism, a striker safety mechanism with a direct trigger interface, a sear with direct striker interface, and/or a striker with integral striker spring retention features.
A firearm having a threaded barrel-receiver connection, with a threaded receiver opening for cooperative engagement with a threaded barrel. The receiver is also compatible with a clamping system for engagement of an unthreaded barrel, so that threaded and unthreaded barrels may be used interchangeably. The threads of the receiver may have a flat crested thread profile for sliding engagement upon installation of an unthreaded barrel.
A muzzle-loading rifle for use with a primer of the type having a shell and a piston fitted within the shell and adapted for igniting gunpowder in the rifle to fire a bullet. The rifle includes a barrel and a breech plug having an opening for receiving the primer and connected to the barrel. A movable bolt is fitted within the rifle for movement toward the breech plug and adjacent the primer. A spring-loaded primer sealing device is mounted to the movable bolt for engaging the shell of the primer and for pressing against it to help seal the end of the movable bolt to the shell of the primer to control the travel of gases and residue. The spring-loaded primer sealing device is mounted to the movable bolt for engaging the shell of the primer only and does not engage against the piston portion of the primer.
An open ignition breech plug for a muzzle-loading firearm. The open ignition breech plug includes an internal body portion for removable installation into the breech end of a barrel of the muzzle-loader, and an external body portion comprising a gripping surface, a nipple for receiving an ignition source such as a percussion cap, and at least one open portion of the external body portion for external visibility of the nipple and a percussion cap mounted thereon. The nipple can be integrally formed with the external body portion or removably mounted thereto.

The nipple can be integrally formed with the external body portion or removably mounted thereto.
A dart gun for medicating or tranquilizing animals, which includes a barrel and a breech plug, the barrel including a bore defining a longitudinal axis extending from a muzzle end to a breech end, and the breech end including a breech plug chamber and a notch. The breech plug is removably engageable with the breech plug chamber and includes a plug member, an extractor, and a baffle member. The extractor provides convenient loading, firing and ejecting of a blank firing cartridge that is used to fire the dart from the barrel. The baffle rod provides for muffling the sound of the explosion of the blank firing cartridge, and reduces the amount of heat and flames that are exposed to the dart when firing the blank firing cartridge.
A bolt assembly for a firearm, wherein the bolt assembly is intended to move inside an inner cavity of a receiver of the firearm and comprises a body, a removable bolt head, at least one protruding element that tends to protrude elastically from the body, so that when allowed to protrude elastically unhindered, the bolt assembly cannot be inserted inside the inner cavity of the receiver. The connection of the bolt head to the body causes the protruding element to elastically contract, enough to allow the bolt assembly to be inserted inside the inner cavity of the receiver. Thus, a single elastic protruding element enables the user to be warned if trying to assemble the body without the bolt head into the receiver.
F41A 17/42 - Safeties for locking the breech-block or bolt in a safety position
F41A 3/18 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks hand-operated
F41A 3/36 - Semi-rigid bolt locks, i.e. having locking elements movably mounted on the bolt or on the barrrel or breech housing
