last time i'll be starting a topic, but i'm at the end of my rope trying to figure out whats going on with my mp7. I was in my local pro shop and got a maple leaf bucking, but it doesn't create a good enough seal for the gun to fire right so I tried to unswell the stock bucking. used dawn first, alchole next no change, used toothpaste next, no change. just got done test firing and it still acts like the hop up and plunger aren't doing it's job. it still shoots to the right and there doesn't seem to be much dialing in as far as the hop up. I did notice when i took it apart at the pro shop that the hole for the plunger in the inner frame wasn't drilled right and allowed the plunger to get stuck, I filed it down till it would compress and decompress without getting stuck. The last thing i'm going to try before i just give up and sell "as is", is get another stock bucking. i've went through this gun 10 to 15 times and can't find whats going on.
