Hello,
A few weeks ago I broke the rear receiver cover (part #23) in an unfortunate gravity related incident (dropped the gun). This week I received a replacement part from KWA, and I disassembled the rear cover before I understood how to put it back together.
As you can see in the diagram it looks pretty easy to all the parts back in. However, I cannot get the placement of the spring (part #118) correct in the receiver cover. Without it the collapsible stock release will not work.
Any ideas?
