Hey guys I just picked up a square back receiver Mak-90 and I was thinking about replacing the stock with a Bakelite side folding kit. Would like to keep the trigger since it's nice. May also want to install a spiker also. That or maybe replace the front sight base and handguard retainer to mount a bayonet and cleaning rod. Thread barrel for a flash hider. Anything I'm forgetting? To stay 922R compliant what would you all recommend?

Sounds like you got everything.

I will add one warning about the bakelite.  I am not an expert and I don't know if there are different types of bakelite, but the bakelite stock I put on my MAADI AK would dissolve if hit with gun scrubber spray.  I was cleaning it one day years ago and got some of the spray on the foregrip and it started dissolving.  It is still on the rifle, I just won't use gun scrubber on it.

Any ideas where I can get the front sight base, gas block, handguard retainer I'll need that can fit my barrel? I see Polytech sells a spiker front sight base with bayonet. But I can't find a regular style one. Not sure where to get the other parts either.

I think I read something years ago that some Bulgarian FSB are the correct diameter.
Check your barrel diameter in the front. It looks turned down pretty far and might not have enough material to thread.

Ended up finding a Polytech barrel front end. So now I'm thinking to thread the Mak-90 barrel and swap out the hand guard retainer, gas block, and front sight. Oddly enough this Polytech front sight has open ears and not an enclosed circle. Must be an early version like the Legend.

That or I could swap out the complete barrel and drill the gas part. I guess if you swap the barrel you'd have to headspace it.

Yes and before anything - check both barrel diameters to make sure they are identical. You need to find a real Ak gunsmith. I think you’re going to spend more than just selling and buying a preban Norinco.

Yeah true it's a fairly costly project. Unfortunately the prices on the pre-bans are crazy high these days. Checked the barrels have an identical diameter so we are good there. Got the Bakelite furniture kit in today. It looks brand new.

Finally finished this project with help from a fantastic local AK smith Iron Curtain.

I had a Thumbhole Monstrosity during the ban years. I should have kept it and rescued it from the Brady insanity by replacing the bad features with good features.

Bought a cheap bayonet online, however it wouldn't fit this Chinese gun. I think the thicker Chinese barrel was the cause for this. So a little Dremel action and now it fits!!
