Crosman 1377/1322 Suppressor Kit

***PLEASE READ THE FULL DESCRIPTION BEFORE PURCHASING!***

Please note that this adapter is not compatible with standard suppressor threads. It is made with a much coarser M20X2 thread pattern that makes it better suited for a polymer to polymer connection. The good news is that the compatible suppressors are very low priced!

This listing is for a threaded adapter/barrel band, thread protector, and UNI Suppressor for the Crosman 1377 or 1322 airgun. The suppressor has an expansion chamber and 8 cone-shaped interior baffles that significantly reduce the report of this airgun. The suppressor 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 Houston, TX. They use Multi Jet Fusion to print the part and bead blast it to give it a nice finish. I 3d print the Suppressor and Cap in ABS at my home in Texas. It also includes a set screw and allen key for securing the barrel. So it is an improvement over the stock barrel band.

If you have any issues with accuracy there are usually two causes:

1. BREECH SCREW: It is likely the most despised feature on the 13XX and likes to come loose. Open the bolt and you’ll see the head of the breech screw where you would place a pellet. You will need a .05″ allen key to tighten it.
2. MISALIGNMENT: I used to make the suppressor with a larger opening than necessary to avoid any clipping issues and to compensate for misalignment, but have decided to tighten it up for maximum report suppression. This will increase the likelihood of pellet clipping if there is the slightest bit of misalignment. There are many factors that can lead to misalignment (most of which will be on us), but rest assured that we will not leave you hanging if you have any issues. Let us know and we’ll take care of you!
