Marcus Geezer; I did chop the egg down till it was about 1cm from the body of my Ion. You kind of have too otherwise like you said it is about 18" off the gun! I don't see why this would cause a feed problem though. Most manufacturers try and make sure their products work without the user having to hacksaw it It's not the weight it's self its the way that the weight sits, the feedneck at the front and all the weight (bateries e.t.c.) at the back causes problems.
