very disappointed
I purchased 4 mbx magazines and all of them at first use give me problems brand new out of the packaging,the springs stick down and all the shots fell down into the magazine,i dont know why the springs stick from pushing upwards,and also gives me a double feed at times,these magazines is definitely bad for me because i cannot afford to use this in competition matches,i am very disappointed after spending so much money for them,im not sure if they need tuning or what but i dont know how to do that,i only wish i can return all of them,very disappointed. RE: Let us get you in contact with MBX to see if they can get you taken care of. Be on the lookout for an email that I will copy you on. Response from Chuck- You did buy 2 from us and 2 from somebody else it appears. SO for all 4 not to work there has to be something else causing it. We have had very good results from MBX. I did send you an email and copied MBX on it.
