Which 80% receivers does Ghost Gunner use?

GG2 can machine any mil-spec AR-15 or DPMS 308 lower receiver with a pre-milled rear take down well. It also accepts 1911 single stack government and Polymer80 PF940C frames.  We recommend the lower receivers we sell here.  Note: you can also program the machine to finish your own custom jobs.  We cannot currently recommend anodized lowers or frames, but for additional information on anodized lowers please email us at [email protected]

How much does Ghost Gunner cost?

The total cost of the machine is $2,000 before shipping is applied. 

What tooling does Ghost Gunner use?

Ghost Gunner uses industry standard ER-11 collets to secure end mills and drill bits. Changing tooling is a simple process and full instructions are included.

How is the work piece held on the table?

Injection-molded jigs are used to hold the work piece in place as each milling step is performed. T-slot nuts are inserted into the t-slot rails to anchor jig bolts in order to secure the work piece to the table upon insertion into the T-slot rails.

Can Ghost Gunner do engraving?

Yes, GG can be programmed to engrave with popular softwares. For GG-compatible engraving services we recommend GhostWriter by Komar Enterprises.

What is included with my Ghost Gunner?

All new Ghost Gunner 2 CNC mills include the following: 6 ft. USB A-B cable, 6 ft. IEC C13 power cable, ER11 collet nut, 17 mm wrench, 12 mm wrench, 3 mm ball-end Allen wrench, and 5/16 in. Allen wrench. A DD USB flash drive containing software and weapon milling programs is included with machines shipped within the US.

What else do I need to buy for the machine to work?

Plug the Ghost Gunner CNC machine into your computer via the USB cable and connect the Ghost Gunner’s power cable. Install our software and use any compatible .dd design file (See minimum system requirements here). For finishing guns, you’ll need to provide the 80% lower receiver or frame and all other firearm parts.  Additionally the Ghost Gunner 2 does not ship with any jig sets, so you will need to add one jig set for each type of 80% lower or frame you wish to mill. The machine is also fully programmable if you want to complete your own projects.

How fast can the machine run?

When cutting aluminum, there’s little reason to cut as fast as possible. For example, many machines that claim to cut aluminum do so by cutting as fast as possible at depths of just 0.001″, which results in poor part tolerance, as only the tip of the end mill actually cuts the metal. The result is the end mill tip dulls quickly and then part quality suffers. Ghost Gunner is designed to cut deep grooves and thus doesn’t require a nonsense feed rate to overcome inadequate design. To directly answer the question, Ghost Gunner can run fast (80ipm), but doesn’t need to, as it’s rigid enough to cut like a real CNC.

Do I need a special power supply?

No. Ghost Gunner uses a standard IEC power cord and is compatible with any 110/220V circuit. No external power brick is used; the machine is entirely self contained.

How do I connect to Ghost Gunner?

Ghost Gunner has two ports: Power (IEC standard) and USB (Type ‘B’).

What sort of maintenance is required for Ghost Gunner?

Ghost Gunner’s moving parts are entirely sealed from chip debris. All bearings are sealed and contain wipers to prevent foreign contaminate entry. The rails are stainless steel and are factory lubricated, but do require periodic wiping to prolong life. End Mills dull over time and are considered a consumable. With proper use, end mills should manufacture approximately 8 to 10 AR pattern lowers before needing to be replaced. Emptying the chip tray by use of a shop vac or similar after each build will prevent chip overflow (shaved aluminum chips occupy approximately 15 times their solid volume).

Is manufacturing a firearm legal?

In general, yes. Semi-automatic firearms, including the AR-15 lower receivers, are generally legal to manufacture for private individuals under federal law. However, some states/municipalities restrict either the manufacture of certain firearms, or, more recently, the personal manufacture of a firearm with a 3D printer and/or CNC machine. GG makes no claim regarding your local manufacturing legalities. In some localities, lower receiver files provided by Ghost Gunner may require special licensing to manufacture and/or possess.

Under federal law, manufacturing firearms for purpose of sale and distribution without an FFL is prohibited. Without an FFL, you should manufacture firearms for personal use only. Recent ATF determinations have signaled that allowing others use of your CNC equipment may itself constitute manufacturing, therefore Ghost Gunner advises GG owners to neither print firearms for other individuals, nor allow other individuals to use their Ghost Gunner to manufacture firearms without the advice of counsel.
