M99 Issues

[VS]

Woo, I'm having some problems with my SW Barrett M99! Here's our list so far.

-Trigger: The gun likes to not fire, as in the trigger is impossible to pull. I pull my bolt back, bring it forward, and when I try to pull the trigger, it's impossible to do so. Recocking the rifle always fixes this problem.

-Bolt: Sometimes the bolt is incredibly hard to bring up, and incredibly hard to pull back as well, as if something won't let it come back. With enough force (see: A LOT), the bolt will come back and then go forward again.

-Hopup: The hopup likes to undo itself and return back to the zero-hop position. This, I'm sure I could fix with tape.

For now, it's just a really cool rifle sitting on my floor; until I can find out what's wrong with it. If anyone's got any info on what's causing these problems, and what'll fix them; I'd appreciate your input. I've taken it apart, everything seems to check out just fine.

For the record, this rifle uses Maruzen APS2 internals and NOT APS2-L96 style.
