Fn pbr ????

[Mot45acp]

I have a FN PBR in .308. 18" barrel with brake. My question is what thread pitch is the barrel threaded to?

TIA

Every mention of it I can find with a quick google search says 5/8-20.

While it's possible that FN uses a 5/8-20 thread on it's brakes I have never heard of that.

5/8x28 are common threads for MB's on the larger contours.
