I have a 7mm from Gunwerks and I ordered a Ultra 7 CB suppressor. I have 1/2" thread on the end of my gunwerks barrell. I want to us the suppressor on it along with a Christensen arms I have. The question i have is the suppressor is a 5/8" screw on and my barrell on my gunwerks is 1/2". What thread adapter do you recommend for this application.
