I gave Colin a call yesterday about these moderators, and as I was working in his area, he kindly invited me over to the machine shop to see the mods in various stages of manufacture. All I can say is that I am very impressed with the build quality of them and the attention to detail that goes in to the manufacture. Each one is hand made and custom made to customers requirements. I will definitely be ordering one soon to mount on my 6mmBR.
Thanks again Colin
Cheers,
Jinks.
