some of the 07 ar31's came with a hush kit on them and some of the 32's had them also,and as far as the grip the ar31 has a pretty big grip on it but it feels good in your hand,the ar34 has a thin very comfortable 2piece side plate grip like my truth has,I still have not shot the brute yet but I want to some guys on pse forum says its a good shooting bow...........Ted
