20090007767 | Soft-Projectile Gun Barrel and Method for Making Same - A method for making a gun barrel for soft projectiles includes providing a mandrel for the bore of the barrel. The mandrel is inserted into a barrel base that can be connected in use to the receiver of a soft-projectile gun. The connected barrel base and mandrel are inserted into a tube. A resin, preferably reinforced, is poured into the space between the inside of the tube and the mandrel. The barrel base, mandrel and tube are surrounded by a pressure chamber. A vacuum is applied to the pressure chamber to de-gas the resin. Then a positive pressure is applied to the pressure chamber to force the tube against the mandrel and resin to form the desired barrel. The mandrel may have rifling impressions. The tube may have a mold shape for forming an ornamental design in the outside of the barrel. Barrels made by the method are also disclosed. | 01-08-2009 |

The barrel insert has a proximal and a distal end, the distal end adapted to engage a proximally disposed projectile disposed in the barrel. The barrel insert also defines an expansion volume for propellant gases for launching the proximally disposed projectile at a predetermined velocity. | 12-01-2011 |

20110088540 | FIREARM SUPPRESSOR BOOSTER SYSTEM - A booster system including a piston housing, a piston, a spring, and a rear cap attached to the piston housing. The piston housing includes an annular outer wall and an annular projection extending inward from the outer wall at a rear end of the piston housing. The piston is disposed within the piston housing and includes a bore and a radially outwardly extending flange at its front end. The spring is radially disposed between the piston housing and the piston in a space enclosed by the outwardly extending flange and the annular projection. The rear cap includes an end wall extending radially outward from a rear end of the piston housing. A side wall extends forward from the end wall and hangs over the outer wall of the piston housing at a radial distance from the outer wall of the piston housing. The sidewall of the rear cap includes an engagement surface for attachment to a body of a silencer. | 04-21-2011 |

20100043628 | Projectile for a Stacked Projectile Weapon - Clips for use with projectiles and projectile stacking systems in which individual projectiles are clipped together to form a stack are disclosed. The projectiles may be joined individually by a user before loading in a barrel, or during a loading process assisted by features on the breech of the barrel. The tail of each projectile includes a set of clips which engage the nose of a trailing projectile in the stack. Projectiles may be withdrawn from barrel and unclipped as required by the user. | 02-25-2010 |
20100251881 | IM-lock for weapons having preloaded projectiles - A weapon having a barrel or launch tube and a projectile preloaded therein. An element prevents accidental firing of the projectile if the weapon becomes overheated. | 10-07-2010 |
20100313743 | FIREARM ATTACHMENT LOCKING SYSTEM - A locking system for a firearm attachment. The locking system having a rotating lock ring having a lock-and-release lever rotatably mounted thereto. The lock-and-release lever having a lock engagement surface optimally configured to forcefully engage a locking surface when in a locked orientation. The locking ring having a nonconcentric engagement surface that repositions in a radial direction when the locking ring rotates and the nonconcentric engagement surface is configured to engage the muzzle of a firearm for locking the muzzle attachment thereto. | 12-16-2010 |
20110005376 | TUBE WEAPON - A tube weapon comprises a weapon tube arranged in an exchangeable fashion using screw thread at a breech block of the tube weapon, and a cradle tube in which the weapon tube is axially and displaceably positioned. Despite using screw thread for connecting the weapon tube with the breech block, prevention of axial, and preferably also radial play, are assured, whereby the weapon tube is removable via a cradle tube in the front. The weapon tube is pre-loaded in the stress direction, which occurs with firing stress by a screw thread ring arranged in front at the breech block. The screw thread ring encircles the weapon tube and is preferably partially screwed in detachable fashion into the anterior end of the breech block facing the weapon tube muzzle, and efficiently supports itself, axially, with its anterior end located before the breech block against a collar of the weapon tube. | 01-13-2011 |
20110011253 | Stress Induced Crystallographic Phase Transformation and Texturing in Tubular Products Made of Cobalt and Cobalt Alloys - A method of producing a cobalt-based tubular product includes forming a cobalt or cobalt alloy tubular workpiece having at least about 30% by weight of fcc phase and subjecting the workpiece to at least about a 20% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process. The metal forming process may include radial forging, rotary swaging, pilgering and/or flowforming. A gun barrel includes a tubular component made of a cobalt-based superalloy material. The component has at least about 25% by weight of hcp phase with basal planes radially oriented perpendicular to an inner diameter of the component. | 01-20-2011 |
20110056363 | WEAPON WITH IM-CHARACTERISTICS - A weapon having a barrel or launch tube for a projectile or shell preloaded therein together with a propellant charge. An active vent is configured on the barrel for preventing accidental firing of the shell if the weapon becomes overheated. | 03-10-2011 |

20140283673 | FIREARMS FOR FIRING SHOTSHELL TYPE AMMUNITION - Shotshell type ammunition includes a hull, a sabot disposed within the hull, and at least one projectile disposed within the sabot. The hull has a rimless first end that includes a primer for firing the ammunition. The hull also has a seat surface for seating the hull against a complementary seat surface in a firing chamber of a firearm. The seat surface is located a distance from an outer end surface of the hull at the rimless first end. The hull further includes an outer cylindrical side surface extending from the rimless first end of the hull to the seat surface of the hull. Methods of fabricating such ammunition includes forming such a hull, providing one or more projectiles within a sabot, and disposing the sabot with the one or more projectiles therein at least partially into the hull. Shotgun type firearms are configured for firing such ammunition. | 09-25-2014 |
20160033225 | Removable Barrel and Hand Guard for Modular Rifles - A kit for use with a modular weapon having a barrel and having an upper receiver defining a gas port and a barrel opening. The kit comprises an upper receiver plate for attaching to the upper receiver, and a barrel plate. The weapon barrel passes though concentric openings in the upper receiver plate and the barrel plate and is secured in the opening within the barrel plate. Another opening in the barrel plate receives a primary gas tube such that a rearward segment of the primary gas tube extends rearwardly from that opening and a forward segment of the primary gas tube extends forwardly from that opening. A forward end of a gas tube extension couples to a rearward end of the primary gas tube and a rearward end of the gas tube extension is received within the gas port when the kit is in use with the modular rifle. An assembly removably attaches the upper receiver plate and the barrel plate thereby creating a gas flow path beginning at the gas port and comprising the gas tube extension, the rearward segment of the primary gas tube, and the forward segment of the primary gas tube. | 02-04-2016 |
20160138882 | Barrel with Cam Followers - A barrel for a semiautomatic firearm operating under the short recoil system has one or more cam followers projecting outwardly to engage one or more cams positioned on an inner surface of a slide surrounding the barrel. Interaction between the cams and the cam followers controls the angle between the longitudinal axis of the barrel and the axis of motion of the slide to prevent the breech end of the barrel from moving too far as the barrel tilts as it unlocks from the slide, ensuring that the extractor will engage the rim of a spent casing and extract it from the chamber during recoil. | 05-19-2016 |
