I think you already know the answer.
You've let us know how you feel, now it's time to let the seller know.
1) What were you expecting?
2) What were you suppose to get and what did you get?
3) What work wasn't done to the the part?
1) i was expecting a 28" .25 barrel on a disco receiver
2) i got a 26" .25 barrel,a disco receiver .25 bolt,35gn pellets,50gn bullets.the bolt handle was switched to a stock crosman bolt handle
3) when i said part it is meant as i didnt change anything
i guess i cant cry over a replaced bolt handle since i got some bullets and pellets
wont bother the seller unless there is something wrong with the set up.
