This adapter allows you to screw on an airgun suppressor with 1/2 x 20 threads. 

I recommend going with the Ronin 1/2 x 20 with this gun. I have it installed on my personal gun and it works flawlessly. However, results may vary and might need modification to work in semi auto mode. This gun is similar to the Bullmaster and others have been able to fix the issue by replacing the spring. Go to your hardware store and look for a lighter spring. I got mine from Ace hardware and it fixed the magazine indexing issue.
