| 145 | Semiautomatic firearm | US14599396 | 2015-01-16 | US09810496B2 | 2017-11-07 | Ivan Kolev; John Linscott |
| A semiautomatic firearm with redundant systems for reducing misfirings. A safety trigger is provided that is passively actuated in advance of a firing trigger. The safety trigger maintains redundant safety mechanisms that prevent inadvertent or accidental actuation of the firing trigger. The firing trigger can be configured for actuation with a very low magnitude or “soft” pull without compromising safety. For the disclosed embodiments, the safety trigger assures that the firearm is discharged only upon deliberate actuation of the firing trigger. In one embodiment, a trigger pull adjustment mechanism provides adjustment of the pull of the firing trigger to a desired force required by the operator. The disclosed trigger pull adjustment mechanism reduces the number of components and complexity of the machined parts over conventional trigger pull adjustment mechanisms. | ||||||

| In weapon shot is fired during counterrecoil. The counterrecoil energy damps the recoil energy. During recoil, the breech block is unlocked, the spent cartridge case is ejected from the barrel by the residual pressure of the powder gases and is directed by a deflector into a hole in the gun carriage. When recoiling into the aftmost position, the barrel approaches the projectile and locks it by means of the breech block. Meanwhile, the next cartridge is taken from a magazine. In the event of misfire, the barrel, continuing to counterrecoil, actuates an extractor for removing the defective projectile. A recoil imitator returns the barrel to the aftmost position, where it is loaded with a projectile in a manner similar to the post-firing recoil. The technical result is ability to load the weapon automatically before firing or to reload the weapon automatically in the event of misfire. | ||||||

| A locking and recocking assembly with swivel breech-lock and rotating locking head particularly designed for inertially-actuated weapons, which combines in a single assembly all the functions for locking, opening, case ejection and recocking with locking return, required for correct operation of the weapon; those functions were, until now assigned to various components variously assembled on the weapon. The locking and recocking assembly with swivel breech-lock and rotating locking head has the entire mass, required for inertial operation, concentrated in the swivel breech-lock, which is accommodated completely within the supporting structure of the weapon, such as the sheath or barrel extension or breech of the weapon. All this leads to better balancing and stability of the weapon, higher reliability in operation, greater constructive simplicity and ease of assembly and disassembly. | ||||||
