Receiver system for a bolt action firearm, comprising: a receiver comprising a forward end adapted to receive a barrel and a rearward end arranged to receive a breech bolt in a boltway provided in said receiver; a breech bolt adapted to slide linearly in said boltway and to lock to said receiver by rotation when said breech bolt is in a closed position; a buttstock interface block attached at a rearward end of said receiver and adapted to interface with said stock; a trigger mechanism provided in said buttstock interface block and arranged to cooperate with a cocking piece 31 carried by a striker provided in said breech bolt.

Bolt assemblies for firearms (e.g., bolt action firearms) and methods of assembling and disassembling same are disclosed herein. In particular aspects, bolt assemblies comprising a bolt body, a bolt handle, a bolt shroud, and a clip that secures the bolt shroud to the bolt body are disclosed. The bolt shroud preferably resists removal of the bolt handle from the bolt body.

The invention relates to handguns (mainly sports and hunting) and is a magazine-fed firearm in which the magazine is located above the trigger and at an angle to the vertical plane. This solution allows to reduce the length of the firearm, while not complicating the process of installing the magazine.

The invention relates to hand firearm and is aimed at improving the ergonomics of firearm with a bullpup layout.

The specified technical result is achieved by the fact that the bolt of the firearm has an extension of the bolt handle, which makes it possible to position the bolt handle near the trigger, thereby facilitating the process of reloading the firearm.

A bolt action AR rifle can be prepared using a standard AR lower assembly and coupling it to a bolt action upper assembly. The bolt action upper assembly has a bolt action receiver containing a bolt. The method of forming a bolt action AR rifle can include: providing the bolt action upper receiver assembly; providing the standard AR lower AR receiver assembly having a pivot pin and takedown pin; inserting the pivot pin into the pivot pin receiver hole; pivoting the bolt action upper receiver assembly at the pivot pin until the takedown pin is aligned with the takedown pin receiver hole; and inserting the takedown pin into the takedown pin receiver hole.

A modular bolt assembly may include a bolt body, a striker assembly, and one or more removable bolt, head having a floating fixing pin, The removable bolt head may have a cartridge engagement surface, a back end that removably mates with a bolt body, and a floating firing pin with a front end that contacts a cartridge primer, and a rear end that receives force from the striker assembly. Bolt heads may be included for different caliber cartridges, allowing the modular bolt assembly to be used with different types of ammunition, the floating firing pin prevents the striker assembly from directly contacting a chambered round without the bolt head, thereby preventing catastrophic failure during use if a boll head is not present and properly positioned.
