Abstract
A bolt action firearm includes a bolt assembly with a bolt body having an outer surface defining a longitudinal guide channel extending along a length of the bolt body from a rearward end to a forward end. A receiver defines a central longitudinally extending bore for accommodating the bolt body. A bolt guide is configured to be coupled to the receiver. The bolt guide includes a projection configured for traveling in the guide channel when moving the bolt body in the receiver so as to ensure that the bolt body is at a predetermined correct angular orientation within the receiver.
Claims15
A bolt action firearm, comprising:
- a bolt assembly including a bolt body having an outer surface defining a longitudinal guide channel extending along a length of the bolt body from a rearward end to a forward end;
- a receiver defining a central longitudinally extending bore for accommodating the bolt body;
- and
- a bolt guide to be coupled to the receiver, the bolt guide including a projection configured for traveling in the guide channel when moving the bolt body in the receiver so as to ensure that the bolt body is at a predetermined correct angular orientation within the receiver;
- wherein the outer surface of the bolt body further defines a second guide channel adjacent to a rearward end of the longitudinal guide channel and extending circumaxially partly about the bolt body, the projection of the bolt guide being configured for traveling in the second guide channel to enable the bolt body to be rotated between open and closed positions when the bolt body is fully inserted within the receiver.

- a bolt assembly including a bolt body having an outer surface defining a longitudinal guide channel extending along a length of the bolt body from a rearward end to a forward end;
- a receiver defining a central longitudinally extending bore for accommodating the bolt body;
- and
- a bolt guide to be coupled to the receiver, the bolt guide including a projection configured for traveling in the guide channel when moving the bolt body in the receiver so as to ensure that the bolt body is at a predetermined correct angular orientation within the receiver;
