Lower Receivers

GFY Lower 

A lower you can depend on...

The GFY Lower Receiver is where classic design meets rigid construction. Lowers have bulk material where it matters, and precise fitment where you want it. This billet piece of 7075 aluminum is sure to take a beating, and remains compatible with most upper styles. However, it would probably look best with our GFY Upper Receiver! 

Flexibile to your needs...

Variance work and customizability.

Looking to add an ambidextrous magazine release? Or maybe just your logo and company engraved on the side?
