CO2 and Green Gas powered air pistol owners can now easily mount a red dot or reflex style optic to their blowback or non-blowback air pistol. This mount attaches to most air pistols that are equipped with under-barrel Picatinny accessory rail. Umarex’s Universal Bridge Mount features 7-slots and clears the pistol’s slide so any blowback operation is unaffected. Be mindful when installing that it may cover the safety lever on some models.
