Polymer receivers offer several advantages over aluminum receivers.
First, the polymer is much lighter than aluminum. This can be important for rifles that are intended to be used for long periods or those that need to be carried for long distances. Polymer receivers also tend to be more durable than aluminum receivers, and they can withstand more abuse without being damaged. Finally, polymer receivers are less expensive than aluminum receivers, making them an economical choice for those who are looking for a quality receiver.
