Appreciate the data. I will be breaking it down next week to refinish the stock. I did some research on forums like this and that is why I settled on the QB. Originally looked at the Tech 99 which was twice the price of this one and the specs didn't justify the cost. I understand the Tech 99 has a better spring, but I am just doing some plinking and getting the attention of the few varmints that venture into my yard. So far the QB has turned out to be a pleasant surprise.
