Composite Effect Bushing

Composite Effect Bushings – MinCom X-Series Holders

The Composite Effect Bushing is the black, moon-shaped insert that installs inside the aluminum MinCom X-series holder and interfaces directly with the mortar tube. It is a functional component of the holder system, not a simple spacer.

These bushings are manufactured from a low-creep composite material designed to maintain its shape under long-term load. Unlike common plastics, the material does not cold-flow or take a permanent compression set, allowing consistent performance across multiple seasons of use.

The composite material provides controlled compliance, which increases surface contact and holding effectiveness while absorbing recoil and vibration from repeated firing cycles. This helps maintain consistent tube retention without loosening over time.

Composite construction also provides corrosion resistance, quiet operation, and tolerance to dirt and moisture, making these bushings well-suited for outdoor rack use.

Each bag includes ten 30 mm bushings and ten 40 mm bushings for use with MinCom X-series holders.
