A low-cost, reduced friction expanding bullet (160) with an improved core retention feature (130) and a method of manufacturing the bullet (160) is described wherein a cylindrical jacket (100) containing a compacted malleable metal core (110) having an open end (105) and a closed end is forced into a forming die having a bottleneck shaped interior resulting in a bottleneck shaped pre-form (1 14) wherein the outside diameter of the open-ended forward portion of the jacket (100) is smaller than the outside diameter of its closed rearward portion and wherein a transition shoulder (125) separates the two diameters. The pre-form (114) is then placed in a profile die (148) wherein a base punch exerts an axial force against said pre-form (114) which axially collapses a portion of the jacket wall forward of the transition shoulder (125) subsequently forcing said portion of the jacket wall radially inwardly providing a reduction in bearing surface and forming an internal core-locking radius while at the same time forming an ogival bullet nose (150). The bullet (160) thus formed provides reduced friction and ultimately higher muzzle velocity per any given chamber pressure level while also providing a core-locking feature (130) comprising a wide- area, circumferential indentation (130) which serves as a living hinge (163) that ultimately expedites uniform bullet (160) expansion.

This facilitates faster initial ignition of the propellant of the ammunition, and consequently allows higher performance levels to be achieved. Other advantages regarding other applications of this invention include cleaner burning loads, greater economy, and lower perceived recoil.

A projectile (110) is provided with a projectile tip (120) having enhanced aerodynamic properties to improve accuracy of the projectile. The tip has a body having a base or lower end (128), an upper end (133) and a curved, side wall (163) between its upper and lower ends that defines an ogive tip length. The tip is received with a projectile jacket (140) and also can have a series of aerodynamic features (155) formed in its body to modify air flow about the body of the projectile in flight.
A piston assembly (200) is provided for a gas-operated firearm of the type having a chamber and a barrel. The piston assembly includes a gas expansion housing (217) and a piston (232) mounted within the gas expansion housing. An annular recess (235) is formed in the outer wall of the piston to receive exhaust gases diverted from the barrel upon firing of the firearm. At least one longitudinally extending groove (237) extends from the annular recess to the head of the piston and forms a pathway for diverting the exhaust gases to the head. of the piston. During firing, pressurized gases are diverted into the annular recess and expand longitudinally from the annular recess to the piston head, whereupon the pressurized exhaust gas drives the gas piston rearwardly along the housing.
An improved firearm including a non-detachable, pivoting magazine is disclosed. The magazine (80) is pivotally attached at its rear end to a sliding arm (90). The sliding arm (90) is slidably retained within the magazine well (70) of the firearm. The sliding arm (90) is configured to move upwardly and downwardly within the track to allow the magazine (80) to be raised into and lowered out of the magazine well (70). When the magazine (80) is lowered out of the magazine well (70), the magazine (80) can be pivoted about its pivotal connection (110) with the sliding arm (90) such that a front end portion of the magazine (80) pivots downwardly and rearwardly to allow ammunition cartridges to be loaded into and unloaded from the magazine (80).
A receiver-stock connector (5) allows for secure attachment of various stocks to firearm receivers. The receiver (110) can be configured so that firearm components can be mounted in the receiver through an open rear end (112) of the receiver.

A firearm holding device has a body with a first arm (17), a second arm (19) spaced from the first arm (17), and a bend (23) connecting the first and second arm (17, 19). The first and second arms (17, 19) are adapted for engaging the firearm (S) in clamping engagement when the firearm (S) is received therebetween.
This invention encompasses articles, compositions, and methods that provide enhanced corrosion resistance and wear resistance to firearms, firearm components, and firearm accessories. In one aspect, for example, a substrate (1) comprising a firearm component is coated with a first layer of a corrosion- resistant material (5) such as a first metal, followed by a second thin film layer of an abrasion-resistant material (10) such as a second metal, a ceramic material such as a metal nitride, diamond-like carbon material, or other materials.
A shell stripper assembly (10,40,60,80) includes a shell stripper (10) , a stripper guide (40) , a stripper guide plate (60) , and a magazine insert (80) . The shell stripper (10) strips the top round from the firearm magazine (290) so that it can be picked up by the firearm breech bolt (280) . The shell stripper (10) slides between guide rails of the stripper guide (40) , and its motion is controlled by the stripper guide plate (60) .

A firearm safety system prevents an unintentional discharge of a firearm. A touch sensor (12) is located on a front surface of the firearm trigger (10) and has a conductive touch pad for sensing contact by a user of the firearm. A touch sensing electronic circuit is coupled to the conductive touch pad and trigger and prevents the firearm from discharging if contact with the conductive contact pad is not sensed. Additionally, the safety system can be configured to conserve battery power of electronic firearms by providing a signal to wake-up the system controller.
A swivel connector (10) has the form of a split ring that enables a carrying element such as a sling or strap to be connected to a mounting device such as a sling swivel stud of a firearm. The swivel connector (10) can be constructed of a single continuous piece (15) of elastic material and can have a geometry that reduces rotation of the swivel connector about the mounting device.
