ops inc. collar ID dimension?

[coyotesniper]

can someone tell me what the inside dimension is on the ops inc. collar

I have a barrel that is .730 and wondering if the collar will fit or if I need to have it turned

THANKS

The Mk 12 SPR barrel steps down from 0.7495" to 0.725" at the shoulder for the barrel collar.
