I personally would not risk the scope, take a look at this one it is inexpensive and comes with a one piece mount:Welcome to our Addiction...
I have the Hammers scope & mount mentioned on the Amazon site. Easy setup, easy adjustments, very clear & holds zero well. All together an excellent value. I purchased & mounted it 1 year ago and have shot ~750 pellets using it (the AO markings appear different from when I bought mine).Be aware that the numbers printed on the Adjustable Objective are not accurate on mine. A simple paint dot will fix this when you measure off distance to zero it.Good Luck!
