I am new to the AK-47 world, so I have a few questions that others here may seem as pretty much common knowledge to most people. This question is about 'Front Trunnions'.
1. Is a 'Bulged' front trunnion something related to only Yugo AK's (Zastava), or are they used in many other AK's made in various other countries?
2. Why would a bulged front trunnion be better than a regular front trunnion?
3. Does a bulged front trunnion serve a special purpose that a regular trunnion cannot do?
Thanks for any of your knowledge about this.
