LOWER RECIEVERS

The AR-15 lower receiver is a crucial component, acting as the backbone of the rifle and housing key mechanisms like the trigger group, magazine well, and pistol grip.

It's also the serialized part of the rifle, making it the part legally considered a firearm. The lower receiver connects to the upper receiver, which houses the barrel and other components.
