ASG Picatinny Mounted Pistol Bridge Mount for Reflex Optics

Mounting a reflex sight to a replica air pistol can sometimes feel harder than mounting the sight itself. Many popular CO₂ pistols were designed long before red dots became commonplace, leaving shooters with limited mounting options. The ASG Picatinny Mounted Pistol Bridge Mount provides a practical solution by creating a stable optics bridge that attaches directly to the pistol's accessory rail.
 
Originally designed for replica models such as the CZ 75D Compact, STEYR M9-A1, STI Duty One and CZ 75 P-07 Duty, this mount has also proven popular with owners of the Umarex CP99, P99 DAO and CP Sport. In reality, compatibility is determined less by the pistol model and more by the dimensions of the frame and rail.
 
The mount slides onto the pistol's front Picatinny rail before being secured using four grub screws. Once fitted, it provides an elevated top Picatinny rail suitable for mounting reflex sights, red dots and similar lightweight optics. Two additional side rails are included and can be fitted if required, allowing the attachment of torches or other accessories.
 
Before purchasing, it is important to check your pistol dimensions. The bridge provides approximately 45mm of internal height clearance and 25mm of internal width clearance. Pistols exceeding these dimensions may not fit correctly, regardless of whether they feature a Picatinny rail.
 
Being manufactured from lightweight polymer, this mount should be viewed as a practical mounting solution rather than a precision-engineered competition accessory. It performs its intended role well, allowing shooters to fit optics to replica pistols that would otherwise have limited options available. Expectations should be adjusted accordingly. This is very much a functional means to an end rather than a premium machined mount.
 
The included side rails may be useful for torches, although we generally discourage mounting lasers to the sides of pistols. Due to the offset position, point of impact and point of aim will vary significantly with distance, making zeroing far less consistent than many shooters expect.
 
Please note that the grub screws secure directly against the pistol rail and are likely to leave marks on softer finishes. This is normal and should be expected during installation.

Is This the Right Mount for You?
If you own a replica air pistol with a suitable front-mounted Picatinny rail and want an affordable way to fit a reflex sight, this bridge mount does exactly what it sets out to do. It isn't designed for firearms, competition use, or precision optics mounting, but for airgun and airsoft shooters looking to add a red dot to an otherwise unsupported pistol, it provides a simple and effective solution.
