Abstract

The invention relates to quick acting interfaces that allow for easier transportation and maintenance of precision rifles. Embodiments include an interface with an engaging segment and a receiving segment that engage one another and lock together. The engaging segment may have a series of connective bearings that fit into indentations inside the receiving segment. Embodiments allow a firearm to be modulated such that a barrel of the firearm may be disassembled without the need of any specialized equipment and reassembled without impacting the firearm's accuracy or reliability. Embodiments are scalable such that multiple interfaces can be used to adjust the total length of the firearm barrel.

First claim

1 . A quick-acting modular rifle interface comprising:
a rifle barrel comprising a connection mechanism, said connection mechanism comprising a receiving segment and an engaging segment; said receiving segment comprising a plurality of indentations; said engaging segment comprising a bearing portion with a plurality of connective bearings protruding therefrom; wherein said plurality of indentations receive said connective bearings of said engaging segment when said receiving segment and said engaging segment are coupled together; and wherein said connective bearings retract into said engaging segment to disengage said receiving segment and said engaging segment, allowing said barrel to be deconstructed for stowage and transportation.

2 . The apparatus of claim 1 , wherein said receiving segment and said engaging segment are coupled by threading.

3 . The apparatus of claim 2 , wherein said receiving segment includes receiving thread and said engaging segment includes engaging thread, wherein said receiving thread and said engaging threaded in opposite directions to permit coupling.

4 . The apparatus of claim 1 , wherein said rifle barrel comprises more than one of said connection mechanism.

5 . The apparatus of claim 1 , wherein said engaging segment is permanently affixed to a rifle receiver at a pre-set location.

6 . The apparatus of claim 1 , wherein said quick-acting modular rifle interface further comprises a matching, serialized bolt that has been head spaced to said barrel.

7 . The apparatus of claim 1 , wherein said engaging segment and/or said receiving segment further comprise a barrel extension.
