Polymer receivers have a few benefits over metal receivers.
First, they’re lighter weight. This can be a big benefit if you’re carrying your gun around all day or are going to be shooting it for an extended period.
Second, polymer receivers are less prone to rust and corrosion than metal receivers. This can be a big advantage if you’re using your gun in a wet or humid environment.
Third, polymer receivers are less susceptible to damage from impact than metal receivers. This can be an important consideration if you’re using your gun in a high-risk situation where it may get banged around or dropped.
Fourth, polymer receivers usually have a smoother, more consistent finish than metal receivers. This can give your gun a nicer appearance and may help it run more smoothly.
Overall, polymer receivers have several advantages over metal receivers. They’re lighter in weight, less prone to rust and corrosion, and less susceptible to damage from impact. They also usually have a smoother, more consistent finish. If you’re looking for a receiver that has all of these benefits, then a polymer receiver is a good choice.
