This listing is for a threaded adapter, silencer, and thread protector for the Crosman 1377 or 1322 airgun. The silencer has an expansion chamber and 8 cone-shaped interior baffles that significantly reduce the report of this airgun. The silencer can be easily removed by unthreading it by hand. A cap is provided to protect the threads when the suppressor is not in use. To install you will need to remove the spring roll pin that secures the pump arm and end cap, replace the end cap with the adapter, and reinstall the roll pin.
The adapter is printed in super tough PA12 Nylon by another manufacturer in the US. They use Multi Jet Fusion to print the part and bead blast it to give it a nice finish. I 3d print the Silencer and Cap in ABS at my home in Texas.
If you’d like to 3d print your own, the files are available for download HERE.
Below is a video detailing the installation process:
