摘要： A barrel has a barrel body that extends a barrel length and a bore extending through the barrel body. The bore has a cartridge chamber section and a rifled section with a bore diameter. A cartridge shell fits within the cartridge chamber section and the projectile extends from the cartridge chamber section into the rifled section. The cartridge shell with the projectile has a shell length within the bore, the barrel length is less than twice the shell length. The rifled section has rifling grooves between rifling lands, and each of the rifling lands has a land width. The groove diameter is greater than the land diameter by an amount that is more than one half of the land width. The barrel body has an extractor assembly with an arm retractably extending from a cavity. The arm can rotate in the cavity when extended and does not rotate when retracted.

摘要： A feeding and positioning device for toy gun comprises a barrel and a friction cylinder. The barrel has a bore, a convex hole, and a guiding groove. Two groove sides are formed at two sides of the guiding groove with circular cone shape. A width and a depth of the guiding groove are gradually decreased from the first end of the barrel inwardly. The friction cylinder has a hollow and elastic cylinder body covered at the first end of the barrel and a friction portion arranged inside the cylinder portion and inserted into the convex hole inwardly. The bullet is aligned by the groove sides and then cooperated with the friction portion to form three-point guiding position to downwardly press the bullet to be precisely fed. It may prevent the bullet from skewed error and improve the range of firing, effective potential energy, and hit rate.

摘要： A revolver for firing high velocity ammunition includes a frame, a cylinder, a barrel, and a firing mechanism. The revolver may include one or more of the following, each of which is especially adapted for use in the context of firing high velocity ammunition: spacers for adjusting a barrel-cylinder gap, for eliminating broaching of the rearward surface(s) of the barrel; a forcing cone formed in the rearward opening of the barrel for accommodating deformed projectiles; a reflective surface (e.g., mirrored surface) provided on the cone and/or barrel rearward surfaces, for reducing erosion resulting from using high velocity ammunition; gain-twist rifling in the barrel for a smoother transition to full projectile velocity; a larger diameter, hardened firing pin bushing for minimizing brass flow in the rearward direction; and a front sight assembly that minimizes lateral shift or drift of the sight pin during firing.

摘要： A method of making a gun barrel having a breech end and a muzzle end and a bore extending between the two ends comprises applying to the outer surface of the bore a plurality of swaging dies (5), each of which carries an upstanding helical land (10). The dies are pressed simultaneously against the external surface of the gun barrel such that each land forms a helical recess (14) in the external surface and crystalline deformation to the material of the barrel wall immediately below the external helical recess. The distortion of the external surface results simultaneously in the creation of a plurality of smooth helical ridges (16) on the surface of the bore.
