PerfectParts GLOCK MOS mounting plate
The PerfectParts GLOCK MOS mounting plate is a precision-machined steel adapter designed for Glock MOS pistols, excluding Slim Line models. It creates a secure and stable interface for compact red dot sights, with exact fitment for selected Holosun optics and a low-profile design that keeps the optic close to the slide. For users who want a reliable mounting solution for sport shooting, training, or professional use, this is a smart option to buy.
Built from steel with a compact 2.5 mm profile, the plate adds only 27 g including the mounting hardware, helping preserve the balance and handling of the pistol. The rigid construction supports repeatable alignment and consistent performance, while the black finish gives the plate a clean and durable appearance.
Technical Performance
This mounting plate is engineered to sit securely on the Glock MOS slide and provide a firm base for the optic. The steel body helps minimize flex and movement, which is important for maintaining zero over time. Its low height also supports a natural sight picture and a clean installation.
The included screw system is designed for correct positioning and reliable retention. With proper installation and thread locking, the plate offers dependable use under regular range and field conditions. In practical terms, it is a compact, durable mounting solution that keeps the optic stable without unnecessary bulk.
