Hi all.
Anyone have any experience with Witt muzzle brakes?
Are we allowed to import them in Australia?

That is timing the brake.
Aren't all muzzle attachments timed with a locknut?

They get good reviews, and they're local.
FYI.

The brake on Project 50 is custom made and tuned to the barrel by the smith so it probably won't have a locknut. On the mass produced Barrett offerings there's both a locknut and a clamp but I suspect these are more to allow for proper alignment rather then actual timing.

There's 2 parts to this,
Timing - Ensuring the ports are correctly aligned dead horizontal so as not to create any weird torque action. Can be either precision machined then torqued, Crush washer, Lock nut or combination of crush washer and lock nut.
Harmonics - Distance from crown to first baffle and diameter of bore. This is a dark art that while I'm aware of it I have no great insight into what's involved. I have done some research on barrel tuners and might try one on the 50BR if possible.

They're not shimmed either?
That's a lot of extra work to cut the thread to time the attachment.
It would have to be fitted to each barrel.
