sks mount for scope not extracting/other mount not for scope did extract ?

other camera wasnt on LOL forgot to start the filming
found out why i had put some tape under the mount to firm it up tight on the scope mount recei,ver found out thats not good, because the bolt was rubbing on the reciever cover now just enought to lock the bolt and failed to extract, so i test it without tape on it next time out bet its going to extract btw no more slam fires the trimming of about 5 thounds off the firing pin did the trick

check out video time 1:22 freeze it see the whimmpy extraction of the case with the scope mounted it barley came out, thats because the bolt is rubbing on the reciever mount
