Help ASAP

I was out messing with it today taking some pics (I'll post them later) and I cocked the gun haha well it didn't do what I thought I was going to and it ended up shooting but something is still messed up, as for right now the gun is completely apart and I forgot how I took it apart, so I have to look at a diagram to get it back together.

I'm not sure whats wrong but the sears aren't the problem I think it just needs some lube and a few adjustments.

anyways heres the main problem when I pull back on the bolt it gets stuck, then when I push forward it shoots. but I need to push hard. then now It pulls back hard (I know it needs greased up) and pushes forward again hard but it will shoot. bbs won't get caught though so I don't know whats going down. any suggestions

My buddy's L96 did the exact same thing, I don't know if we ever solved it...I'll have to ask him.
But, just thinking... inspect the cylinder and piston. See if anything, particularly where the spring makes contact, is stripped.

Okay I feel like the most stupid person in the world, I took apart the trigger mech, haha I need to get up to all that before I can say exactly what is wrong with it.

can anybody link me to the assembly guide?
