The work on Cyma AK47

I promised to write more about the work I did on my Cyma AK47S (CM.028) yesterday. So here it goes.

The goal was to:

• put new Systema tightbore,
• install metal body from Cyma,
• install side rail (from Cyma) for side lock mount rail.

I started with the metal body -- I wanted to drill three holes for the side rail. I attached the rail to the body with plastic straps (I have no idea what is the proper word to use), as shown below.

I soon started drilling holes -- I just marked it using my drill.



And then I removed the rail to finish the drilling.





When the holes were made, I bolted the rail.



And then I attached the mount rail.



Then I removed the entire mechbox and all the other parts from the old plastic body. I had some help from this very good video of AK47 disassembly.



At this moment I wanted to remove the barrel and install the tightbore. I followed this video but it was incompatible...

I was very surprised to see that the original barrel in Cyma CM.028 did not have the notches and hole that are used to install the hop-up bucking, as you can see on the video. It was just put inside the hop-up chamber, along with the hop-up bucking! So I didn't install the tightbore. :(

I also had a lot of trouble with installing the mount for stock on the new body. One of the parts didn't fit inside the body. This is the troublesome part. I don't have any file at home so it required some work to make it fit. :(



I finally put everything together. I tested the replica today -- it does work, but I want to change this barrel anyway.
