After trying the XL adapters on the original Wraith they are the same adapters. The manual I have does not say they are so I did not think so. So these adapters here will work on your original Wraith if it is the QD model.

That suppressor has been discontinued for 7 years so the adapters we have in stock are the last of them. So I suggest getting the ones you need and maybe a couple extra if you think you may want more down the road. We are out of stock of the 1/2x28 model but have the other two models in stock still.
