C&H Precision Optic Mounting Plate – Glock Gen6 to Holosun 509T – G6-509T-ST
The C&H Precision G6-509T-ST (UPC: 850071159929) is a specialized, heavy-duty mounting solution designed specifically for the Glock Gen6 MOS platform and the Holosun 509T enclosed-emitter optic. As the Glock Gen6 ecosystem expands in 2026, C&H Precision has engineered this Stainless Steel (ST) variant to provide maximum structural integrity for duty and tactical applications. Because the 509T utilizes a unique clamping rail system rather than traditional vertical screws, this plate is precision-machined to exact tolerances to ensure a "zero-movement" fit, even under the violent slide velocities of high-pressure defensive ammunition.
Constructed from Stainless Steel and treated with a Black Nitride finish, the G6-509T-ST is significantly more durable than standard aluminum plates, eliminating the risk of thread stripping or plate warping. The plate utilizes C&H’s patented Stainless Steel T-Post system for the slide-to-plate connection, ensuring the highest level of thread engagement available in the industry. This low-profile design allows the 509T to sit at an optimized height for a clean co-witness with modern suppressor-height iron sights. Designed and manufactured in the USA, this plate is the premier choice for law enforcement and shooters who demand a "tank-like" mounting solution for their Glock Gen6.
Includes: (1) G6-509T-ST Stainless Steel Adapter Plate, (2) Plate Mounting Screws, and Vibratite Thread Locker.
Key Features
