High‑detail replacement barrels for miniguns, ideal for upgrading GAU‑2B / M134 weapon stations on your helicopter and aircraft builds. These 3D printed barrel sets are designed to replace soft or simplified kit barrels and add crisp, eye‑catching detail where it matters most.
 
 
These Black Ops 3D replacement barrels are designed for minigun installations such as GAU‑2B / M134 weapon stations and are perfect for upgrading kit‑supplied barrels that lack definition. They feature sharply defined barrels and spacing to bring your miniguns up to the same level of detail as the rest of your build.
Use them as spares for your 1/48 CH‑53 / MH‑53 GAU‑2B “minigun” weapons stations set, or anywhere you need more accurate, finely detailed minigun barrels on helicopters or aircraft. Each set is 3D printed in high‑resolution resin to capture small details that are hard to achieve in injected plastic.

Usage notes
Carefully remove the kit‑supplied barrels from the minigun body, clean the mating surfaces, and test‑fit the Black Ops 3D barrel set before gluing. Use CA glue for attachment and make sure alignment is straight along the axis of fire. Prime and paint with your usual metallic and weathering techniques to match the rest of your build.
