Need a little help on thread pitch.

[4xforfun]

I am trying to get a hold of Shawn Carlock to get the exact thread pitch and thread size of his muzzle brakes. I know from past experances that it is hard to find him this time of year because eveadently he liks to hunt. Whodathunkit??? Anyway, He is not answering his phone.

Anyway, if you know off of the top of your head just shout it out!!! Or, of you have a way to measure the thread pitch....... I do know that the threads are .58 inch OD...just need the thread pitch.

Thanks,
Tod Soeby
