What Buyers Ask
What tools are needed to finish this 80% lower?
You will need a drill press or router, a vise, and standard drill bits. The included jig guides the milling and drilling operations. Basic machining knowledge is required.
Is this compatible with all AR-15 upper receivers?
Yes. The G150 is designed to mate with mil-spec AR-15 upper receivers. We recommend checking fitment with your specific upper, as tolerances can vary between manufacturers.
How does the polymer hold up compared to aluminum?
The fiber-reinforced polymer is exceptionally strong and impact-resistant. The primary advantage is significant weight reduction—approximately 60% lighter than a standard aluminum lower—making it ideal for lightweight builds.
