Will someone measure thread length and post

[eseaton]

I am planning on using a suppressor that has 0.067 inches of threading. Will someone who has a threaded version measure the length of the threads so I can plan on further investigating a "spacer" or not.

Who has had to use a spacer and on what kind of suppressor?
I will be using a SWR Spectre. My rifle is ordered but will not arrive for a few days yet.

If I need a spacer, who has these for sale?

Thanks for your help.

Mine is .655 from crown to barrel shoulder.

Seems like this would be the same on all of them but you never know. I may have a 4:30 Friday barrel.

the muzzle brake i have has a lock nut and the lock nut will not thread all the way back

I used these to index my muzzle brake. I gently removed material from a washer to get the index in the right place.

Do NOT use a crush washer. Proper shouldering and sqaureness with the bore cannot be assured. You need a spacer made specifically for use with suppressors. These are about the best deal I've found:

The standard length of thread for the 1/2-28 is 5/8" or .625
.067 = 1/16" or about two threads.
