To mount a Runcam camera on your airsoft long weapon, you’ll need the proper adapters and mounts. Fortunately, this Runcam Bracket w/ Rail Mount and Adapter for Runcam2, Airsoft Version set has everything you need.
The Picatinny mount will work best for assault rifles and other shorter-ranged weapons. On the other hand, snipers can mount the camera to their scopes thanks to a scope adapter. Thus, there’s something for everyone in this package.
