Claim 8:
9. An airgun comprising:
a compression tube including separated forks;
a first pivot extending across the separated forks and a tube fork cam surface;
a magazine positioner adapted to hold a magazine such that a magazine projectile supply is positioned in a loading area between (i) a tube fork side of the magazine positioner and (ii) a bore side of the magazine positioner;
a breech pivotally mounted to the separated forks for movement at least between (i) a closed orientation with the compression tube proximate the breech and (ii) an open orientation, wherein the breech includes a barrel holder positioning a barrel opening on a barrel side of the magazine positioner and having a bolt guide on a bolt guide side of the magazine projectile supply;
a bolt configured to interact with the bolt guide such that a contact surface of the bolt is urged between (i) a loading position on a bolt side of the magazine projectile supply and (ii) a firing position on the barrel side of the magazine projectile supply, wherein the bolt includes a bolt positioner, wherein a position of the bolt positioner determines a first position of the contact surface; and
a biasing system configured to urge a drive surface against the tube fork cam surface;
wherein the tube fork cam surface is configured to interact with a drive bolt positioner to move the bolt such that when the compression tube and the breech are rotated from a closed position to an open position, the contact surface is moved from the firing position through the magazine projectile supply to the loading position, and
wherein the tube fork cam surface is further configured to interact with the bolt positioner to move the bolt such that when the compression tube and the breech are rotated from the open position to the closed position, the contact surface is moved from the loading position through a projectile holder of a magazine in the magazine projectile supply to drive a projectile in the projectile holder to a second position where compressed gas from a transfer tube travels through a gas management system to thrust the projectile through a bore.
