Kalibrgun Snipe issues

OK so before I bought my gun I spoke to chris at AOA he told me they are changing the breach blocks because the breach o rings were not seating right . So apparently they fixed that issue and sent me out the gun., but I would not have thought that has anything to do with the mag o ring blowing out but I could be wrong .
Anyway I'll be calling AOA Monday morning .
 
I'm waiting for my .22 rifle with a barrel length of 600

I studied the manual on the KalibrGun website, there is a description of this problem.
