  • Patent number: 6684547
    Abstract: A recoil dampening assembly for a firearm that includes a bolt assembly and a stock that is linearly moveable with respect to the bolt assembly, includes a plurality of elastically deformable shock-absorbing members having a compression cavity defined therein, and a plurality of rigid spacers interspaced between the shock absorbing members. The plurality of shock absorbing members and rigid spacers are adapted to be placed between a bolt assembly of a firearm and a stock of a firearm. The plurality of shock-absorbing members and rigid spacers are adapted to dampen the recoil as transmitted from the bolt assembly to the stock when a charge that is in the firearm is ignited by allowing each shock absorbing member to at least partially compress within the compression zone.

  • Publication number: 20040007124
    Abstract: The present invention relates to firearms requiring the smooth operation of slidably engaged subassemblies for effecting projectile loading, maintenance, triggering, discharge, or reloading of a projectile. The major drawback of the prior art, such as that applying to slide-action pistols, is that friction occurs unevenly and at high levels between moving parts, which leads to damaging levels of frictive heat, wear, or warping, as well as jamming. The slidable guidance system proposed herein addresses this drawback by employing micro-rollers whose surfaces do not at any one point constantly touch the slidable gun part(s) with which they come in contact. Preferably, at least a set of micro-rollers and a pair of channels are installed in the inner sides of a slide and the upper outer sides of a gun frame, or on the lower face of a slide-housed slidable barrel and the upper face of a gun frame.

  • Patent number: 6662485
    Abstract: A firearm interface for a buttstock and pistol grip that provides a means to attach a pistol grip or a buttstock assembly to a firearm, and shotguns in particular. It can be used for either modality individually or both in combination. It allows the utilization of an M16/M4 style pistol grip and the adjustable, as well as the fixed buttstocks of M4/M16 style rifles and carbines. The buttstock and pistol grip interface confers the ability to configure the firearm to different requirements and to the ergonometric needs of diverse individuals. By facilitating the use of M4/M16 style receiver extensions and M16/M4 style pistol grips the buttstock and pistol grip interface brings a vast array of options to the firearms to which it is affixed. For those individuals with military experience the use of M16/M4 style components imparts a degree of familiarity and utility.

  • Patent number: 6651371
    Abstract: The present invention is a modular stock system for rifles. The system replaces the rifle's buffer tube with a modified one containing a mount for a constant cheek weld and a rail track for adjustment. A hind portion then mounts on the replacement buffer tube. The hind portion is interchangeable depending on the user's needs. Various configurations of the hind portion are discussed, including adjustable stocks, fixed stocks, and specialized stocks. The hind portion may be made even further modular by the addition of rail system.

  • Patent number: 6637141
    Abstract: An improved gun stock construction that substantially reduces both the recoil and the tendency of the gun to move upward or jerk when it is fired. The stock is formed with two sections having a flexible hinge mechanism. This structure creates a moment arm or couple which opposes the tendency of the gun to move upward when it is fired. This invention relates to improvements in a gun construction and more particularly to the improvement in gunstock that permits better control of the gun by the operator.

  • Patent number: 6618975
    Abstract: A paintball gun conveniently assembled in the present invention has a through hole formed in a back of a grip and communicated with a chamber of the grip; a set bolt having an engagement groove and being extended into the through hole, protruded into the chamber and pressed against a magnetic-attraction plate; a setscrew hole formed in one sidewall of the grip and communicated with the through hole for being screwed with a setscrew, whereby the set bolt designed with different length can be extended into the through hole to push the magnetic-attraction plate, and then screwed with the setscrew tightly so that a push rod of the magnetic-attraction plate can push a locking member to adjust the displacement height of the locking member for different types of the gun bodies, thus a single grip is suited for being conveniently and quickly assembled with a gun body of different style.

  • Publication number: 20030140541
    Abstract: An M16 or commercial equivalent style rifle buttstock is provided with a stowage compartment within the buttstock body for an M4/M16 style firearm or commercial equivalent that utilizes an adjustable receiver extension which is cylindrical with a radially disposed elongated rib. The buttstock can be inserted without any permanent modifications to the host firearm, and is completely reversible. Internal storage for accessories is provided, and the buttstock is able to accept standard M16 style or commercial buttplates, with or without hinged access doors to the stowage compartment. The buttstock provides an improvement to the ajustable buttstock used on M4/M16 style firearms in cold weather which can become frozen in place in the collapsed position and not provide a proper mounting of the carbine relative to the user. Additionally the buttstock provides all of the standard ergonometric relationships of an M16 style firearm or commercial variant for the user.

  • Patent number: 6301817
    Abstract: A strong, durable, lightweight long gun stock comprising a rigid insert molded of reinforced thermoplastic material together with a foaming agent. The insert is over-molded with a thermoplastic material which provides the stock with the desired surface characteristics. The insert is dimensioned with respect to its over-molded surfaces to be smaller than the finished stock and is designed to give maximum strength to the stock. The insert is shaped to promote the flow of the over-mold material and to minimize shrinking, swelling or distortion of the insert. The over-mold material may be a hard, un-foamed material or a thermoplastic elastomer. The hard un-foamed over-mold material mechanically bonds with the insert and provides the stock with an extremely smooth, hard outer surface. The thermoplastic elastomer over-mold material is compatible with the material of the insert and bonds both mechanically and chemically with the insert, providing the stock with a soft, quiet, non-slip surface.
