i'm surprised my buddy cornfed hasn't responded to this thread ,anyway i got the new matrix guide series sight recently after having the regular matrix (plastic pins) for several years ,i did have some problems with the windage bar (dovetail style) which tr fix quickly and for no charge ! the new sight is a great sight as the windage and elevation adjustments are on a worm gear. the matrix is also availiable with the new v drive system check them out imo they are great and customer service is also A one!
