Friend of mine has a flat receiver he wants to use for his Yugo kit build. He asked me if trimming the trunion down on the RPK style trunion would have any effect?

I told him if you don't plan on launching grenades with it, it should be ok like other similar trunions. Was I right?


I told him don't be a cheapskate, go and get the right receiver for that trunnion. But I think he made up his mind. :sad:

Trimming them down is fine. Look at the 1.6 mm global sells.


Getting the real deal is a better solution.

i have heard mixed answers on cutting down the RPK style yugo for a normal receiver. the most popular answer was don't (something to do with the locking lug recesses), but i don't know for sure either way.

I could be wrong about the trimming.

This question was addressed early in the yugo saga.
You risk having the trunion crack.
DO NOT mill it flat.

Get an 80% with bulges and go from there.

In what way would it crack? When pressing the barrel back into the trunnion or just from shooting it a number of times?

Cutting it flat takes material off where the bolt lugs lockup on the trunion.
This makes the one place you don't want to fail weaker.

I has been done and credible reports of cracking have been reported.

That said,you can always try and see what happens for you.
I would check it carefully before, during and after firing to be safe.

Good Luck

Thanks for the info. I'll let him know. Im glad he hasn't started the project yet, maybe now I can convince him to do it right. :smile:
