Introducing the ALU Tube HPA Uppers - a new anodized style!
We wanted to mix up our CRBN uppers in a crazy way - removing the carbon fiber entirely! We did just that, replacing the carbon tube for anodized aluminum, and adding some sleek skeletonized cuts at the front for a super light weight design.
The ALU Tube Uppers feature dual hopup windows, fiber-optic front and rear sights, and CNC aluminum parts. These parts are modular, and interchangeable with any of your CRBN Uppers!
These uppers are a limited run, so they won't be coming back!
