Badger ordnance M2013 bolt knob TPI

Just as the title states. Looking for a definitive answer on what thread pitch the badger ordnance M2013 uses for it's bolt knobs. I'd like to swap mine out but I have no good way of checking at the moment without just bringing my bolt into a hardware store. Any help would be greatly appreciated. TIA
 
Measure the OD of the threads with a caliper.

Then, set the caliper to 1.000”

Place the jaws of the caliper on the threads, count the threads between the jaws.

Obviously your threads aren’t an inch long, so set the caliper to .250 or .500 and multiply by 4 or 2.
