## Abstract

A safety selector assembly for a firearm includes a cylinder sized and shaped to be rotatably received within a lower receiver. The cylinder includes a cylinder end having a recess defined therein, and a plunger disposed at least partially within the recess. The plunger is moveably secured within the recess. The safety selector assembly also includes a lever detachably coupled to the cylinder end by the plunger.

## Claims

### Claim 1

A safety selector assembly for a firearm, comprising:
a cylinder sized and shaped to be rotatably received within a lower receiver, the cylinder comprising a cylinder end having a recess defined therein;
a biased plunger secured within the recess; and
a lever detachably coupled to the cylinder end by the biased plunger;
wherein the lever comprises a head portion having an exterior opening, wherein the exterior opening has a diameter smaller than a diameter of a proximal end of the biased plunger; and
wherein the biased plunger is configured to remain secured within the recess when the lever is detached from the cylinder.

### Claim 2 (depends on 1)

The safety selector assembly of claim 1, wherein the recess extends along a rotational axis defined by the cylinder, and the plunger is biased along the rotational axis by a biasing element.

### Claim 3 (depends on 2)

The safety selector assembly of claim 2, wherein the biasing element is a spring.

### Claim 4 (depends on 1)

The safety selector assembly of claim 1, wherein when the lever is coupled to the cylinder end, the biased plunger engages with a plunger recess defined within the head portion.

### Claim 5 (depends on 1)

The safety selector assembly of claim 1, wherein an outer surface of the plunger comprises an annular groove defined therein.

### Claim 6 (depends on 1)

The safety selector assembly of claim 1, wherein the cylinder end is a first cylinder end and the cylinder further comprises an opposite second cylinder end having a second recess defined therein, and wherein the safety selector assembly further comprises a second biased plunger secured within the second recess, and a second lever detachably coupled to the second cylinder end by the second biased plunger.

### Claim 7 (depends on 1)

A firearm, comprising the safety selector assembly of claim 1.

### Claim 8 (depends on 7)

The firearm of claim 7, further comprising a lower receiver configured to house a trigger assembly; wherein the safety selector assembly is rotatably supported at least partially within the lower receiver and operably coupled to the trigger assembly, and wherein the lever is disposed on an exterior of the lower receiver.

### Claim 9

A method of assembling a safety selector assembly for a firearm comprising:
positioning a biased plunger at least partially within a recess defined in a cylinder end of a cylinder, wherein the cylinder is sized and shaped to be rotatably received within a lower receiver;
securing the biased plunger within the recess; and
detachably coupling a lever to the cylinder end via the biased plunger,
wherein the biased plunger is configured to remain secured within the recess when the lever is subsequently detached from the cylinder.

### Claim 10 (depends on 9)

The method of claim 9, wherein detachably coupling the lever to the cylinder further comprises engaging the biased plunger with a plunger recess defined in a head portion of the lever.

### Claim 11 (depends on 9)

The method of claim 9, wherein detachably coupling the lever to the cylinder further comprises: depressing the biased plunger within the recess; and sliding a head portion of the lever onto the cylinder end.

### Claim 12 (depends on 9)

The method of claim 9, further comprising inserting at least a portion of the cylinder into a receiver of the firearm.
