On the barrel I received yesterday from a MAK 90 parts kit; on the chamber end of the barrel there are basically 2 sections:

Section 1 is on the very end of the barrel, is of uniform OD and has very light machining marks from what looks like when it was originally turned down. It is about 1 inch in length.

Section 2 is also about 1 inch in length, is directly "above" section 1, also has a uniform OD - but this diameter is about 1.5mm or so greater than section 1. This section has a very smooth finish - no machining marks.

In this image if you look on the chamber end of the barrel - yu can see the very end of the barrel, and the slightly raised section above it.

My question is - when you are pressing the barrel into the trunnion - which of those 2 sections gets "gripped"?

Yeah - I talked to Jimmy from Arsenal USA / Global Trades today at a local gunshow - the trunnion presses onto the raised section. Global doesn't have any 19mm trunnions though, and he doesn't expect to import any from Bulgaria for at least 6 months.

well thats a bummer
its not real cost effective to build a mak anyway
by the time your done building it you prob could have just bought 1 cheaper they are only 250-350
if your gonna spend the time to build 1 might as well b a good 1
the price of the kit might b alittle more but all the other parts your gonna have to get are the same wether your building a mak/rom thats worth 250 when your done or your building a bulgi thats worth over 5
just somethang for you to chew on

I found two sources for 19mm trunnions besides Global - one hasn't called me back yet, the other only has 1 trunnion which he was holding onto for his own chinese build; he wants more than I am willing to pay for it. No biggie - I'm RMA'ing the MAK 90 parts kit, and I will just pick up an assembled MAK 90 here locally soon enough.
