Abstract

A lever-action tactical rifle having an upper receiver assembly having a rifle barrel and a hand-guard. A lower receiver releasably and pivotally connected with the upper receiver and having a butt-stock and a magazine receptacle releasably containing a cartridge magazine. A bolt mechanism having a bolt carrier and a bolt member and firing pin being located for reciprocating movement within the upper receiver. A lever-action mechanism is mounted to the lower receiver and is connected with the bolt carrier by an actuating linkage. The bolt member has cam slots being engaged by cam pins of the bolt carrier to translate linear movement of the bolt carrier to rotation of the bolt for bolt locking and unlocking.

2. The lever-action firearm of claim 1, comprising:

an cartridge magazine receptacle being defined by said lower receiver; and

an cartridge magazine being releasably received by said cartridge magazine receptacle and during shooting activities providing a number of ammunition cartridges and positioning an uppermost one of the ammunition cartridges for pick-up by forward movement of said bolt mechanism by said lever-action mechanism.

3. The lever-action firearm of claim 1, said bolt mechanism comprising:

a bolt carrier being located for substantially linear reciprocating movement within said upper receiver and being in assembly with said lever-action mechanism;

substantially parallel guide slots being provided on said bolt carrier and having guided engagement with a guide rails of said lower receiver; and

a bolt mechanism being moveable within said bolt carrier and having a bolt head defining locking lugs and a cartridge recess within which the base of a cartridge is received.

4. The lever-action firearm of claim 3, comprising:

a cam slot being defined by said bolt mechanism; and

a cam pin of said bolt carrier being engaged within said cam slot and reacting with said cam slot during substantially linear movement of said bolt carrier and causing rotational movement of said bolt mechanism for locking and unlocking movement of said bolt head.

5. The lever-action firearm of claim 3, comprising:

said bolt carrier defining front and rear ends and having a generally rectangular cross-sectional configuration, said bolt carrier defining an internal bolt chamber intersecting said front and rear ends of said bolt carrier;

said bolt mechanism having an elongate bolt body defining a firing pin passage and having a bolt head projecting forwardly of said bolt carrier and having locking lugs and defining a firing pin opening;

a firing pin being movably contained within said firing pin passage

a cam slot being defined by said bolt mechanism; and

a cam pin being threaded into said bolt carrier and having an inner bolt actuating portion being engaged within said cam slot and reacting with said cam slot during substantially linear movement of said bolt carrier by said lever-action mechanism and causing rotational movement of said bolt mechanism for locking and unlocking movement of said bolt head relative to a bolt locking receptacle of said lever-action firearm.

6. The lever-action firearm of claim 1, comprising:

said lower receiver having opposed recesses defined by outwardly facing recessed surfaces on each side of said lower receiver;

said lever action mechanism having a pair of drive linkages each being moveable within one of said opposed lower receiver recesses; and

said bolt mechanism having a bolt carrier defining opposed bolt carrier recesses having portions of said drive linkages moveable therein and having driving connection with said bolt carrier for reciprocation of said bolt carrier responsive to manual actuation of said lever-action mechanism.

7. The lever-action firearm of claim 6, comprising:

a lever loop being mounted in pivotal relation with said lower receiver;

first drive linkage members being fixed to said lever loop and each being moveable within said opposed recesses of said lower receiver; and

second drive linkage members each being moveable within said opposed bolt carrier recesses said having driven connection with one of said first drive linkage members and having driving connection with said bolt carrier.

8. The lever-action firearm of claim 7, comprising:

opposed intermediate recesses being defined by said lower receiver; and

side panels being defined by said upper receiver and being spaced from said opposed intermediate recesses and defining elongate slots through which portions of said first and second drive linkage members extend into said upper receiver.

9. The lever-action firearm of claim 7, comprising:

said bolt carrier defining a transverse drive slot;

a bolt carrier drive shaft having end portions each being connected with one of said second drive linkage members and said bolt carrier drive shaft having driving engagement within said transverse drive slot; and

said upper receiver defining a receiver housing enclosing and guiding reciprocating movement of said bolt carrier and retaining said bolt carrier drive shaft within said transverse drive slot.

10. The lever-action firearm of claim 1, comprising:

said lower receiver defining a connection receptacle; and

a connection member being fixed to said upper receiver and having connecting engagement within said connection receptacle and securing said upper and lower receivers in substantially immoveable assembly.

11. A lever-action firearm, comprising:

an upper receiver having a rifle barrel mounted thereto and defining a first pivot mount, said upper receiver defining a protective housing having side panels;

a lower receiver defining external side surfaces and having a second pivot mount;

said side panels being disposed in spaced relation with portions of said external side surfaces of said lower receiver and defining elongate linkage slots;

a pivot member engaging said first and second pivot mounts and securing said upper and lower receivers in pivotal connection; and

a lever-action mechanism being movably mounted to said lower receiver and having drive linkages extending along said external side surfaces and through said elongate linkage slots; and

bolt carrier and bolt mechanisms being substantially linearly moveable within said protective housing of said upper receiver and having driven engagement by said drive linkages of said lever-action mechanism.

12. The lever-action firearm of claim 11, comprising:

a cartridge magazine receptacle being defined by said lower receiver; and

a cartridge magazine being releasably received by said cartridge magazine receptacle and during shooting activities providing a number of ammunition cartridges and positioning an uppermost one of the ammunition cartridges for pick-up by forward movement of said bolt carrier and bolt mechanisms by said lever-action mechanism.
