Oh, I know... Normally I would, but both that KeyMo, brake, and can are all proven on other rifles before. Unless their muzzle threads were cut crooked... I suppose that's possible. But I'll re-torque and try unsuppressed next weekend, if I get time to go up there.Yeah might be the can to barrel connection so might not be the can. Best to try everything before calling them as they will ask you the same things I am sure.
