They need to get a mechbox guide for the SiG series. I tried following the AK-47 since it's also a V3 mechbox, and now my SiG shoots, but doesn't launch BBs out

Now I have to pay a gun doctor to fix it

Now I have $167 worth of brand new parts in that mechbox that are just begging to be put to use, and I have to disappoint them by telling them no, you're not quite ready yet.
The tortue.
I think I might compile a SiG552 mechbox breakdown and reassembly after I learn how to not completely botch mine. Oh the learning process, how I missed thee.
