Ics mag problem
 

I have a ICS m4 for 2 yrs no problems just basic wear and tear. But the past few weeks when I use any mag but my ICS ,it does not seem to feed correctly until I apply light pressure upwards on the magazine. I have tried other brands but I have the same problem. I been using MAGPUL's for a year (plastic) but no go now.:banghead:

You need to remove some of the material from the BB retainer in the mag. Your hopup isn't pressing deep enough into the mag to push the BB retainer out of the way and let the BB's feed.

I'll give that a try
thanks
