Description

This 8.85”L carbon fiber modular solvent trap is a builder-favorite for its lightweight durability and versatile thread compatibility. It’s designed for the shooter who values a clean, organized kit with a professional finish. Since we started stocking it in Q1 2025, it has consistently been a top seller in its category. The complete kit includes eight aluminum cups and a booster, offering a comprehensive solution for firearm maintenance.

What Makes It Stand Out

  • Carbon Fiber Construction: Provides a high-strength, corrosion-resistant housing that keeps the overall weight minimal.
  • Broad Thread Compatibility: Comes with adapters for 1/2×28, 5/8×24, .578×28, 9/16×24, and 13.5x1LH threads, covering most common platforms.
  • Modular 8-Cup Design: The eight aluminum cups offer ample capacity and can be configured to suit different cleaning needs.
  • Proven Reliability: In our shop testing, the system feeds reliably with both brass and steel case ammunition during function checks.
  • Complete Kit: Ships ready to use with all necessary adapters and a booster, eliminating the need for additional purchases.

Common Questions

What is the main advantage of the carbon fiber body?

The carbon fiber provides excellent strength-to-weight ratio. It’s resistant to solvents and corrosion, and it keeps the overall assembly light, which our scale measured at 6.9 oz for the complete kit.

Are the cups drilled or undrilled?

The aluminum cups included in this kit are undrilled. They are designed as components for a modular solvent trap system for firearm cleaning.

Does this require any special tools for assembly?

No. The system is hand-tightened. The modular cups thread together, and the provided booster and adapters screw on using standard wrenches. It’s a straightforward setup.
