My uncle has a Fierce 6.5 creedmoor that is probably 3-4 years old. I am not sure on the exact model, but I know it has a thumbhole stock and a fluted thin(ish) steel barrel with radial brake. He is wanting my help to order a suppressor since I've got a bunch and I'm familiar with the process and hoops that need jumped through. We are looking at trying a GA Precision Jåger suppressor but I don't know what the thread specs are on his Fierce rifle. I have asked Fierce a couple of times with no response. Does anybody here know what threads they use on stainless barrels with the radial brake?
