3D Printed GAU-23/A 30mm Muzzle Brake Replica – AC-130J – 1:1 Scale

Bring a piece of gunship history to your desk, office, squadron, or collection with this 1:1 scale replica of the 30mm Bushmaster cannon muzzle brake used on the AC-130J.

Modeled after the muzzle brake used on the GAU-23/A 30mm cannon installed aboard the AC-130J Ghostrider. The GAU-23 is the aircraft variant of the Mk44 Bushmaster II family of 30mm chain guns.

Modeled at full scale from the real component, this replica captures the distinctive cylindrical shape, three large muzzle ports, and machined details of the original. Each muzzle brake is 3D printed in silver PLA, giving it a metallic appearance straight off the printer without the weight or cost of the real component.

Whether you're looking for a retirement gift, squadron keepsake, aviation display piece, or something for the gunship enthusiast who already has everything, this makes for a unique conversation piece.

The comparison photo shows our 3D printed replica alongside a real muzzle brake to demonstrate the scale and overall appearance of the finished print. The real muzzle brake shown in the photograph is not included.

Good to Know Before Ordering

This item is a non-functioning 3D printed display replica. It is not a firearm component and is not designed, tested, or rated for installation or use on any weapon system.

Because each piece is 3D printed, minor layer lines and small surface variations are normal and are part of the additive manufacturing process. Print color may vary slightly between material batches and photographs.
