As of my last knowledge update in January 2022, I don't have specific details on every product available, and I don't have real-time internet access to provide the latest information on specific products released after that date.

For detailed information on the RMR Beretta Dovetail Optic Mounting Kit, including specifications, compatibility, and any updates or improvements, I recommend checking the official Trijicon website or contacting authorized dealers for the most accurate and up-to-date details. Manufacturers often provide detailed product information, including user manuals and specifications, on their official websites.
