Ordered mine, online two weeks ago and it arrived a week later. It has military look to it but as it was being fixed to an LRS2 I wasn`t too bothered.
I operation, it is much better than I was expecting as it completely muted the recoil on my .308, so much so that I thought I was shooting a .22lr. I have pepper pot / Vais types on other rifles, which though effective, I would go for a Vertebrae any time.
Here is a link to the company`s website (I have no connection to them whatsoever) It cost Eur 130, shipping was Eur 8. Service was fantastic. To order, Just specify the thread size and follow the payment instructions.
