(1) My .308 rifle barrel is 22" and has a diameter (6 inches from the muzzle) of .680". I read somewhere that I should take a measurement that far back from the muzzle. I had wanted a direct 5/8-24 thread but from what I gather on the net, the minimum barrel needed for that thread is .725", so my question is, or my assumption is, that I would need some sort of an adapter, OR choose a different thread. If that's the case, then which is advisable, a different thread, or an adapter?
(2) I read somewhere that the Ruger American Predator that is threaded from the factory, has a barrel size that won't group well with the added weight of a suppressor, especially once a few rounds have been fired. Is that true? And if that is true, then what about my rifle that has the .680" diameter barrel?
(3) Is accuracy lost when using an adapter to fit a can to a barrel?
(4) Please advise me what you would do with my barrel, the .680" and setting it up properly for a suppressor, specifically what you would use etc.
I like the idea of using a 30 caliber can with 5/8-24 threads, and using a direct fit to my rifles that will permit it, but need to know what to do with those rifle barrels that may be a little too thin.
I appreciate any info, and anything else you might like to say about fitting suppressors to different barrel diameters.
first, not sure where you read to take the measurement 6 inches from the muzzle, but that makes no sense. all the threading is done within 1/2 to 5/8 inch of the muzzle. if you barrel is .680 six inches from the muzzle, it is even smaller towards the muzzle where it matters.
you barrel is to small to be threaded 5/8x24. wont be hardly any, if any, shoulder for the can to stop against. no doubt about that. just wont work out.
1/2x28 wont work either. the 308 bore size would leave the material to thin.
the 9/16x24 is a possibility and likely you best hope.
skinny barrel with big bore really complicates things.
never thought using adapters was a good idea. would avoid that route if it was mine.
