Impact FX magazine fit adjustment help

Hi All,



Can someone point me in the right direction as to where I can find a video showing how to adjust the tightness of the magazine fitment on the M3s? I thought mine was normal, but after seeing what others are like to insert and remove magazines, I realize mine is way too tight. I have both the OEM and aftermarket aluminum magazines and they take quite a bit of effort to insert and remove. I remember seeing some time ago about which screws to adjust to fix this, but it didn't seem to work for me, so maybe I'm doing it wrong. I'd like to see if there's an actual video showing this. Thanks in advance!

This quote from a prior post where I had the same problem may help you out. Not on an M3 but it should be the same procedure.

After dumping the pressure in the gun I removed the magazine then loosened all 16 of the screws on the rear butt, including the ones on the sideplates and magazine release plate. Then I pried lightly between the rear block and butt plates. This gave the magazine a bit more room and as I held it in place, I then tightened all of the screws back down. Both mags fit again. Thumbs up.
