I have a wasr 10 hard chromed I picked up from classic arms. Shot it for the first time today. There seems to be about an eighth or sixteenth of an in play between the mag and the release. If I place my hand on the the front of the mag and pull back while firing no issues or jambs. However if I let it hang and hold onto the front grip it jambs? Side to side no movement in the magazine the movement is in the front to back. Any help would be great!
