I think those are still going to be way too short. Unless you are playing back on a football field lol.
messed around a bit more today. Added some ball slots on the side and turned the feedtube so the slots are on the picture side. I also shortened the feedtube pretty much to the max. Still holds 11 balls.
I also tried my hand at an addon compensator. Not sure if like.
CJ - I am not seeing the gaps you were talking about. I removed a space between the upper and lower that didn't need to be there behind the feedblock. But thats all I am seeing. Unless you are talking about the "joint" between the upper and lower tube.
