View Full Version : Xpansion chamber for Sonix Pro

I bought a spyder sonix from ****s about a year ago and just now wanted to add an expansion chamber on it. The "vertical adapter" and expansion chamber that came stock on the gun look funky and that it wouldn't accept an after market expansion chamber without getting a new adapter. Here are pics of the stock vertical adapter and expansion chamber. If anyone has any suggestions or knows what I am talking about let me know.

you can either get a new VA or a trinity or cp reg adapter, they'll both run about the same.
