1. A system, comprising:
a ram configured to mount in a blowout preventer; and
a packer assembly configured to form a seal between the ram and a bore formed through the blowout preventer, wherein the packer assembly comprises:
a packing element formed of a first material, wherein the packing element extends from a first end to a second end along a longitudinal axis and is configured to expand along a lateral axis to form the seal; and
a first insert formed of a second material different from the first material, wherein the first insert supports the packing element and is coupled to a surface of the ram via a key-slot interface positioned between the first end and the second end of the packing element along the longitudinal axis,
wherein the ram comprises a receptacle and the packer assembly is configured to move within the receptacle,
the packing element further comprising a second insert, wherein the second insert comprises a rounded surface configured to engage a corresponding surface of the receptacle,
wherein a protrusion of the key-slot interface is configured to slide within a slot of the key-slot interface to enable the packer assembly to move within the receptacle, and the protrusion is configured to engage an end of the slot to block movement of the packer assembly within the receptacle, and
wherein the protrusion is disposed on the surface of the ram and the slot is formed in the first insert.
