I seem to be having issues with my Tavor cycling through to pick up the next round. I'm using pmags but it also had the same issue with the magazine provided by IWI. I've shot it on two different occasions and cleaned it both times. I've seen people filing down the back of the pmags and they say it helps with the bolt picking up the next round. I guess before doing the filing the pmag would actually bump and hold open/move the bolt open device. Just seeing if someone has experienced this or has advice. I really don't want to start filing down pmags. I'm going to use a GI mag next time and see if it also has this issue. After 100 to 150 rounds, it just seems to have issues. I even cleared a jam today but another person was shooting it. I don't recall another jam. I'm using Winchester, American Eagle, and I actually need to do a better job writing down or keeping track of what is showing the most issues. Everything is brass. Thanks!
