Well with your guy's help I figured it out!!!!!!!
I had somehow mixed up the screws that hold the front and back ring bases on and after taking the scope off , found out that they are two different lengths!!!! i.e. the front screws are shorter than the back screws and I had put the long screws in the front mount which would not let the bolt go closed!!!!!!! STUPID ME!!!!........
Any way thank you guys so much for your help and ideas, and thank you graybeard for a super great forum!!!!!!!!!!
