What is a 'Bulged' Front Trunnion? ... Any advantage over regular trunnion?

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.

Ron,

To my knowledge only Yugo's (M70 for example) used them. They are easy to spot by their bulged sides vs the flat sides of a normal trunnion, which requires a receiver specifically designed for them.
As to why, I assume that it was done for some perceived advantage in strength since they were used with a 1.5mm receiver, probably because they had GLs

THE M70 USES PRETTY MUCH THE SAME TRUNION AS A YUGO RPK. IT IS HEAVIER OVER THE LUGS AN IS ARGUAbLE A STONGER PIECE IN EVERY AREA OF ITS CONSTRUCTION BOTH IN STENGTH AN IN WEIGHT . i

It is of little importance IMO on a 7.62x39 or 223 weapon as a standard akm trunion is plenty strong .

Unless you really think you need a baynet for zombies or you want the cool mall ninja effect Id skip the bayo an buy ammo with the money . if there is a simular gun that uses the same ID GB an the GB in yours is in the correct locsation Is likely doable . does your gun haver a gas shut off GB for gernade launching ?

Im sure you can get one on there some how if you really wanted to .


ODDLY A SAIGA 308 HAS A BULGED TRUNION BUT ON SIDE .
