Modular ar-type safety selector with lever mounting pins

A method of using a safety selector lever assembly for a firearm, comprising:

• inserting a selector core through an opening on a side of a receiver of the firearm, wherein the selector core comprises:
• a first elongated section having a curved face and at least one angled face;
• a first extension, wherein the first extension is positioned at a first end of the selector core and protrudes through the opening on the side of the receiver;
• wherein the first extension comprises a first extension aperture;
• removably coupling a first lever to the selector core, wherein the first lever comprises a proximal end, a distal end, a first recess shaped and sized to receive the first extension of the selector core, a first pin aperture positioned at the proximal end, and a first detent, and wherein removably coupling the first lever to the selector core comprises:
• positioning the first lever such that the first extension is received in the first recess of the first lever;
• inserting a distal end of a first pin through the first pin aperture of the first lever, wherein the first pin comprises at least one notch;
• and
• pushing the first pin such that the distal end of the first pin passes through the first extension aperture and past the first detent of the first lever, wherein at least a portion of the first pin passes through the first extension, and wherein the first detent is received within one of the at least one notch of the first pin.

A firearm configured for a selectable fire rate, the firearm comprising:

• a receiver having at least one opening and a firing assembly;
• a safety selector lever assembly, the safety selector lever assembly comprising:
• a selector core having a first elongated section, and a first extension positioned at a first end of the selector core, wherein the first extension comprises a first extension aperture and is shaped and sized to protrude the opening;
• and
• a lever removably coupled to the selector core, where the lever comprises:
• a first recess that is shaped and sized to receive the first extension;
• a first pin aperture and a second pin aperture positioned on opposing ends of the first recess;
• a second recess comprising a keyed detent;
• and
• a pin comprising a notch;
• wherein removably coupling the lever to the selector core comprises:
• inserting one end of the pin through the first pin aperture such that it passes through the first pin aperture, the extension aperture, and the second pin aperture, wherein at least a portion of the pin extends past the keyed detent and the keyed detent is received within the notch of the pin;
• and wherein rotation of the lever results in a corresponding rotation of the selector core, and wherein the lever is rotatable between a plurality of positions, each position resulting in a different orientation of the first elongated section with respect to the firing assembly.
