Can see behind bolt
I bought a Maverick 88 yesterday, and gave it a detailed cleaning. After a frustrating reassembly, in which I scratched some pieces and got a few badly stuck several times, I got it back together. However, I realized, with the action completely closed, there's some visible space behind the bolt, large enough for junk to fall into. As this is my first shotgun, I assumed the ejection port would look similar to my rifles (i.e. completely closed). Is this okay?
