Our custom engraved lower receiver starts out as a 7075 T6 aluminum billet milled to DPMS Gen 1 dimensions and tolerances.  This allows the receiver to accept standard AR308 parts and magazines.  We’ve further enhanced the design by flaring and broaching the magwell to allow for faster magazine changes, integrating the trigger guard for less parts and assembly, and threaded the takedown pin detent hole to accept a 4-40 set screw.  The lower can be assembled traditionally where the end plate retains the takedown pin detent and detent spring, or the set screw can retain the spring and detent.  This allows for disassembly of the receiver extension without having to worry about losing the detent or spring.  An additional advantage is the ability to set the amount of force the detent exerts on the takedown pin.

Each lower is custom engraved to customer specifications.  Everything is customizable.  The fonts used, the fire control group markings, logo, serial number, and model number are all laser engraved to customer specifications.  Engraving is accomplished with a fiber laser, and can either be the traditional deep engrave or a surface anodize removal that leaves white markings.

After placing the order, we will contact you to begin the design process.  Prior to marking the lower you will be sent a 3D rendering showing size and placement of all markings.  Once approved, your lower will be laser engraved, anodized to Mil-Spec and shipped to the FFL of your choice.  The lead time on this process is dependent on the complexity of the design and the workload at our anodizer, but we make every effort to complete this process as efficiently as possible.  Lead times are currently running about 3 weeks after you place your order.  “In Stock” means we currently have the raw materials required to complete your lower.
