C&H Precision GL509TST V4 Glock MOS to 509T Adapter

Glock MOS to Holosun 509T Adapter Plate

The C&H Precision GL509TST V4 is a precision-engineered mounting adapter designed to bridge the gap between Glock MOS-pattern slides and Holosun 509T footprint optics.

Manufacturing Excellence

Each adapter plate is precision machined to exacting tolerances using HAAS CNC equipment. The manufacturing process includes multiple quality control checkpoints to ensure consistent performance and reliability.

Construction & Materials

• Plate Material: Mild grade steel, black anodized finish
• Hardware: Stainless steel fasteners for corrosion resistance
• Finish: Durable anodized coating protects against wear and environmental exposure

Practical Application

If you own a Glock with MOS (Modular Optic System) cuts and want to mount a Holosun 509T red dot, this adapter provides a secure, repeatable mounting solution. The precision machining ensures proper alignment and zero retention.

Why It Matters

Adapter plates must be manufactured to tight tolerances—even small deviations can affect optic alignment and zero stability. C&H Precision's commitment to precision manufacturing means you can trust your sight picture downrange.
