Thanks, that combination was my design. I sent him the parts and a drawing of what I wanted it to look like and he did the work. To answer your question the B package from
Great Western is $350, the
Shrewd varmint brake is $70 and the
Brockman sight another $75. I forget what he charged me to machine the angle on the rear of the brake and mount and index the sight/brake combination but it wasn't a lot more and the new sling studs added like $10-15 three years ago. The whole setup is as accurate as my eyesight allows. He has three photos of my Mini in his gallery.

Edit: The rear sight was from accuracy systems. Honestly if money is tight I'd start with a trigger job and then add an Accu-Strut when you have the money.
