bought on of these, brand new.
first time out of the box, on rail, not even fully into the first turn, the left side rods came off and bent before I could stop it.
sent to Walthers service dept.
they repaired/replaced and did so for no cost due to it being brand new.
but, it took 6 months and the same free service will not be provided again.
warrantee was only for first repair.
Walters was going to charge me $125.00 until I shared with them the info again about it being new.
that would have been just shy of what I purchased it for in the beginning.
to be honest, I am afraid to take it out of the box and run it.
I think there is a design flaw that causes this to happen.
perhaps I am paranoid
but it seems like I find many of these needing the same fix.
best wishes with yours.
sincerely
Gary
