A lower receiver assembly configured to allow a single firearm to use different shaped magazines firing a variety of ammunitions having different shapes and calibers, the lower receiver assembly configured to couple to an upper receiver of the single firearm, the upper receiver comprising an ejection port, the lower receiver assembly comprising:
a front lug configured to couple to a forward portion of the upper receiver, the front lug comprising a front lug groove at a rearward portion thereof and a front lug aperture extending through walls on either side of the front lug groove;
a trigger guard portion configured to couple to a rearward portion of the upper receiver, the trigger guard portion comprising a trigger guard groove at a forward portion thereof and a trigger guard aperture extending through walls on either side of the trigger guard groove;
a first interchangeable magazine well housing comprising a first magazine chamber at an interior thereof, the first magazine chamber dimensioned to receive and hold a first ammunition magazine for holding ammunition of a specific shape and caliber, the first interchangeable magazine well housing further comprising a first flange comprising a first aperture at a forward portion thereof and a second flange comprising a second aperture at a rearward portion thereof;
wherein, when the front lug and the trigger guard portion are coupled to the upper receiver, the first interchangeable magazine well is configured to be removably coupled to the front lug and the trigger guard portion such that;
the first flange is received by the front lug groove and the front lug aperture and the first aperture are in alignment, and
the second flange is received by the trigger guard groove and the trigger guard aperture and the second aperture are in alignment.
2. The lower receiver assembly of claim 1 , further comprising:
a first mechanical fastener configured to extend into or through the aligned front lug aperture and first aperture of the first interchangeable magazine well, and
a second mechanical fastener configured to extend into or through the aligned trigger guard aperture and second aperture of the first interchangeable magazine well.
3. The lower receiver assembly of claim 1 , further comprising:
a second interchangeable magazine well housing comprising a second magazine chamber at an interior thereof, the second magazine chamber dimensioned to receive and hold a second ammunition magazine for holding ammunition of a specific shape and caliber that is different than the first ammunition magazine, the second interchangeable magazine well housing further comprising a first flange comprising a first aperture at a forward portion thereof and a second flange comprising a second aperture at a rearward portion thereof;
wherein, when the front lug and the trigger guard portion are coupled to the upper receiver, the second interchangeable magazine well is configured to be removably coupled to the front lug and the trigger guard portion such that;
the first flange is received by the front lug groove and the front lug aperture and the first aperture are in alignment, and
the second flange is received by the trigger guard groove and the trigger guard aperture and the second aperture are in alignment.
4. A method of assembling a firearm receiver comprising:
providing an upper receiver comprising an ejection port;
providing the lower receiver assembly of claim 3 ;
coupling the front lug to a forward portion of the upper receiver;
coupling the trigger guard portion to a rearward portion of the upper receiver;
coupling the first interchangeable magazine well housing to the front lug and the trigger guard portion;
inserting a first ammunition magazine for holding ammunition of a specific shape and caliber into the first magazine chamber;
removing the first ammunition magazine;
decoupling the first interchangeable magazine well housing from the front lug and the trigger guard portion;
coupling the second interchangeable magazine well housing to the front lug and the trigger guard portion;
inserting a second ammunition magazine for holding ammunition of a specific shape and caliber that is different than the first ammunition magazine into the second magazine chamber.
