In my previous article I checked out some airsoft parts from Russian Airsoft parts manufacturer, Combat Union. Overall I really appreciated the attention to detail reflected in their work. Although there were some fitment issues, I really liked the look and set out to prep them for installation.
There is something about metal AEG internal upgrades. Personally I think it is the looks. A company from Russia has been making some really shiny internal replacement parts and I just had to get my hands on some.
