I don't see how to push the bolt out from the bottom. the bolt has aournd 1" of play where I can slide it back and forth but it seems to firmly hit against something that will not let me release it fully. I cant get the the spring or spring release because that sits all the way inside the housing and my hand is too big to fit in there. Can't even see any spring release it is so deep inside the housing. there must be a release, I just can't find it
