MANUFACTURED TO ORDER. 8-10 Week Delivery.
Precision machining meets awesome styling in the form of the ONYX™ billet receiver and builder sets. Machined from Certified 7075-T6 Aluminum Alloy and Anodized Type 3 Class 2 Deep Black, these set are carefully tumbled and then blasted with a proprietary media to create a satin smooth finish.
Receivers ship with  a nylon tipped rear lug tension set screw and Bolt Catch retainer screw.
Magwells are properly broached with an internal flare making speed reloading more efficient and the rear takedown pin area has a spot face machined into it, making it easier to push the pin through the receiver.
The ONYX™ features our proprietary ultra smooth upper receiver bore with a barrel extension area that is deliberately undersized for super tight barrel fit and the features are machined in a single operation for perfect concentricity and alignment.
SMOOTHCAM™
The Cam Pin recess has been radiused and blended with the top channel to create a smooth flowing surface.
Each set comes complete with our CP-R360™ Dome Head Cam Pin that reduces wear and friction for smoother operation.
Upper & Lower parts fit is excellent as you would expect from a matched set. 
 
All lower receivers require a valid FFL to ship to.  Please visit our FAQ page for more information when ordering.
