DTA's suppressor was designed to work with the muzzle brake, as well as the rest of the DtA system. you will not find a more accurate can to put on a DTA, nor will you find a more accurate DTA than one with a DTA suppressor attached to it. It's kind of like a camera's lens. There is several pieces of glass in there to make that image sharp and contrasty. Take one piece of glass out and you lose your clarity. Also... If you add a piece of glass, such as a teleconvertor, you still get an image, but it's not as sharp as the image without the teleconvertor.
I also have a 5/8 threaded can, but I ordered a DTA can as well. I bought a DTA for accuracy so there's no reason to compromise that accuracy by using attachments not made for the system.
