RE: barnett sent me a email....
My Quad 400 has had it's share of quality control problems. Upon receiving it i found out that the flipper that holds the string cocked was mounted backwards. The scope reticle fell apart after a few months. The biggest probem withmy Quad 400has been the scope attachment to the stock. It is not a good way of mounting a scope and i've had to re-zero itmany times. Killed several hogs and deer with it and then put it in the attic as a back-up. Now hunt with a Barnett Revolution XS that i bought cheap. This is a very good crossbow in every respect.
