One significant factor in deciding which one will work best for you would depend on its construction materials. Aluminum has been used by manufacturers since time immemorial because it offers better durability than polymer varieties but could hurt your pocket more than its plastic counterpart.


Durability would also be another consideration when selecting between aluminum vs polymer variety; although both offer exceptional longevity against daily wear-and-tear scenarios like weather elements exposure or mishandling accidents during transportations etc., there might have differences in their respective strengths and weaknesses.


Another crucial aspect would be compatibility issues where some receivers may not fit correctly with some models due mainly due based variations from one manufacturer to another. Therefore, it's imperative to ensure that you choose a lower receiver that is compatible with your AR-15 rifle.
