assembling a Mak90 parts kit

[Bigben]

I have a chance to get this parts kit, but cant tell what flat/rivets to use. Advice please?

Chinese trunnions were made for 1.3m flats. People have used 1.5m flats and shaved down the trunnion or flat to fit. No one makes a 1.3m flats regularly (tho it has been done), It's been a sought after item for a few years now. Kinda surprised no one makes one atm.

you could file that down by hand if you had to. It's only .0035" per side

So which flats are you talking abotu that will work if the trunnions were shaved? what about rivet holes and such? are they all the same?

i think mak-90s use a diagonal rivet pattern the others use a side by side

I used 3/16" rivets to build mine, I cut them to the length I needed. You'll run into problems squeezing the 2 rivets inside the barrel journal. That journal is only 19mm, I had to make a custom tool to get those done. Also the tools from ak builder that are used to line up the long rivets are not big enough unless you use the smaller ak builder rivets. I have my own custom tooling that I can adapt to rivets up to 5/16".
I got my receiver from Matt (Turbothis)

The front trunnion uses 1 long rivet and 4 short rivets like the Yugos.

Any 762 flat without the predrilled holes will work if you mill (narrow down) the trunnions. You might need to cut the metal where the top brake is at the front trunnion. On my kit at least the metal just slides along the trunnion, there's nothing tucked like the euro patteren guns.
