I have a Quad 400 AVI I bought new 01/12/2011 it was very acc. Have shot it around 20 times before putting a HHAspeed dial on it which jacked the scope up where you don`t have to lean your head over. Started setting the 3x9 scope and first shot 6" high adjusted and 2nd shot dead center and a big supprize!! the front end broke off the stock where the quiver mounts on. Sent the bow back to Barnett on 2/14/11 Shot fine other than that.Hasn`t been returned yet ,maybe Tues. I hope and maybe with a newer style stock that want break.
