Full product description
Paste this into the main description field and adjust any exact mount locations to match how you designed the parts (ramp, sponsons, side doors, etc.).
The GAU‑18 is a lightweight .50 caliber machine gun used on heavy‑lift and special operations helicopters, including CH‑53 and MH‑53 variants. This Black Ops 3D set captures that weapon in 1/48 scale, giving your Sea Stallion or Pave Low build the correct “fifty” instead of generic or simplified kit guns.
Designed specifically for CH‑53 / MH‑53 models, these 3D printed parts provide crisp detail on the receiver, barrel, and mounting hardware so your door and ramp guns look as serious as the rest of your build. Use them to replace soft kit weapons or to convert an unarmed kit into an armed aircraft.

Installation and use
Carefully remove any kit‑supplied gun parts and test‑fit the GAU‑18 assemblies in the intended door or ramp locations. Clean up support remnants and dry‑fit mounts before gluing. Use CA glue for attachment, ensuring alignment along the weapon axis, then prime and paint with your usual metallics, gunmetal tones, and weathering to blend them into your overall finish.
