TM 416D Bolt lock issue

[clumpyedge]

Here is my problem I've got a problem with my TM 416D my friend took it apart ( as he did with his) to put in a new spring and a new gear set (his works fine).

 

When I finish a mag the bolt lock pops up to indicate the mag is finished but when I put a new mag in it doesn't seem to want to fire. The bolt lock when I put in a fresh mag (after finishing one) seems to just go back flush against the lower receiver rather than staying up allowing me to push it back in which should be the normal function....

 

I was advised by john at fire support it could be something to do with two pins inside the gear box that have been put in the wrong way round?

 

any idea's or help would be greatly appreciated

sounds to me like it's sticking somewhere rather than badly assembled. I'd recommend opening it up and putting it back together, Richard Young from Eagle6 did a really good tutorial on the bolt catch assembly here:
