## Abstract

A device including a body coupled to a magazine receiving area of a firearm and a locking unit that locks a firearm to the body of the device.

## Claims

### Claim 1

A device comprising:
a body configured to be coupled to a magazine receiving area of a firearm; and
a locking unit;
wherein the body includes a pinion coupled to an upper rack and a lower rack.

### Claim 2 (depends on 1)

The device of claim 1, further comprising a bolt blocker.

### Claim 3 (depends on 2)

The device of claim 2, wherein the bolt blocker is located at a top of the body.

### Claim 4 (depends on 3)

The device of claim 3, wherein the bolt blocker includes an engagement area.

### Claim 5 (depends on 4)

The device of claim 4, wherein the engagement area is configured to hold a bolt carrier of the firearm via a firearm bolt blocker.

### Claim 6 (depends on 4)

The device of claim 4, wherein the engagement area is configured to hold the bolt of the firearm via a bolt catch of the firearm being in contact with the engagement area.

### Claim 7 (depends on 1)

The device of claim 1, wherein the locking unit is coupled to the pinion.

### Claim 8 (depends on 7)

The device of claim 7, wherein the locking unit changes a position of the pinion to generate a locked state and an unlocked state for the device.

### Claim 9 (depends on 1)

The device of claim 1, wherein the body further includes a key lock pin.

### Claim 10 (depends on 1)

The device of claim 1, further comprising one or more bushing coupled to the pinion.

### Claim 11 (depends on 1)

The device of claim 1, further comprising a base.

### Claim 12 (depends on 11)

The device of claim 11, further comprising one or more attachment devices to couple the base to a structure.

### Claim 13

A device comprising:
a body configured to be coupled to a magazine receiving area of a firearm; and
a locking unit;
a bolt blocker, the bolt blocker including an engagement area, the engagement area configured to be coupled to a gun bolt blocker; wherein the engagement area has a U-shaped first plane and a rectangular shaped second plane where the rectangular shaped second plane is configured to contact the gun bolt carrier stopper and hold the gun bolt blocker in a firearm bolt locked position.

### Claim 14 (depends on 13)

The device of claim 13, further comprising an upper rack configured to enter a magazine release level area.

### Claim 15 (depends on 13)

The device of claim 13, wherein the locking unit is a code locking unit.

### Claim 16 (depends on 13)

The device of claim 13, wherein the locking unit is a biometric locking unit.

### Claim 17 (depends on 13)

The device of claim 13, wherein the locking unit is a voice recognition system.

### Claim 18

A device comprising:
a body configured to be coupled to a magazine receiving area of a firearm, the body includes a pinion coupled to an upper rack and a lower rack;
a base and one or more attachment devices to couple the base to a structure;
a locking unit, the locking unit is coupled to the pinion where the pinion is configured to move the upper rack into the magazine release level area;
a bolt blocker located at a top of the body, where the bolt blocker includes an engagement area, the engagement area is configured to hold a bolt of the firearm;
wherein the locking unit changes a position of the pinion to generate a locked state and an unlocked state for the device.

### Claim 19

A device comprising:
a body configured to be coupled to a magazine receiving area of a firearm, the body includes a pinion coupled to an upper rack and a lower rack;
a base and one or more attachment devices to couple the base to a structure;
a locking unit, the locking unit is coupled to the pinion where the pinion is configured to move the upper rack into the magazine release level area;
a bolt blocker located at a top of the body, where the bolt blocker includes an engagement area, the engagement area is configured to hold a bolt of the firearm;
one or more warning sensors configured to detect at least one of authorized actions and unauthorized actions; and
one or more processors configured to transmit via a transceiver at least one of a warning signal and a status signal;
wherein the locking unit changes a position of the pinion to generate a locked state and an unlocked state for the device.
