Thanks for the reply Jrsybowhunter.I have been waiting for someone to fill me in on what they found with the mach 4.I have had several threads on sites and only a couple of people have responded.
I am in the process of ordering one for my razortec and I am also interested in the preformance side of the rest .Did you have to fine tune the factory setting on the rest on installation (the sensitivity setting) or just bolt it on and go
thanks again
Jason
