is this gap a problem?

[izzy]

I noticed when taking pictures for the SBR thread. There seems to be a pretty decent gap between the end of the upper and the beginning of the hand guard on this rifle. To recap this is a KAC SR-15. It was hard to get pictures of it but I think you'll see what I'm seeing. Should I fix or have this fixed? Or is this the way it's supposed to be?





eta: it isn't loose at all, there is no play in the hand guard at all
