not for nothing but ,i have to agree with mlaubner, i just got the new guide series matrix without the "v drive" it works just fine and dandy. i don't know why you would need it with a multipin sight? they do make it in a single pin model called the mantis ,i believe it is also a pendulem sight go to trophyridge for more info.
OOPS sorry i thought you were talking about a sight also,my bad
if you are talking about the drop zone ,now that is an awesome rest!
