Need to replace a complete barrel assembly on my MAK-90 but don't want to wait 3 months.  Any reputable builders taking work out there that might have a quick turn around for a barrel replacement?

If I may ask what happened to your barrel?

Nothing, just want to de-ban it (922 compliant, of course)!

Of all the other parts that could be replaced, why would you want to get rid of the original barrel? Is there something physically wrong with it?

I'll be using a ploytech, original so to speak.  The one I have does not have a threaded barrel, provisions for a plunger to retain the barrel nut if I were to thread the barrel and no provisions to retain a cleaning rod.

Are you even allowed threaded barrels in NY?

You don't need to replace the barrel. You need to thread the barrel and install a new front sight base.

As long as I'm 922r compliant and the rifle is pre 94 I can have all the legal features.

I can't find a front sight base for it anywhere with the cleaning rod forks.

Look a little harder.  They pop  up on the EE often.

You're going to an extreme just to "de-ban" your MAK-90.  The Chinese military actually didn't have threaded muzzles most of their Type 56 rifles, anyway.  When folks "de-ban" and start threading their muzzles or getting a threaded muzzle-type barrel, they're actually just getting them to look like the commercially imported semi-automatic versions, not at all like the military-issue Type 56 rifles.

At any rate, if you go that route you just need to swap out the front sight base and the gas block.  Keep your original Chinese barrel if at all possible.

I thought they just used muzzle nuts on the military versions mostly? In that case, I've seen quite a few Type 56's with no bayonets so all you would have to do is swap out the furniture.

10-4 guys, I thought the parts I needed were impossible to find, that's why I opted to change the entire barrel.  

Will a Russian t3 fsb and gas block fit my barrel?

Thought some 56's had threaded barrels and some didn't, and they all had the spiker.  Please chime in with info.

OK I get where your coming from.

Do a lot of research on this style rifle and find out what is right.

And like what's been mention, take your time and look for the part(s) you want/need. Post "want ads" on here and any other forum you belong to or want to belong to, and watch GunBroker as much as possible.

All type 56 assault rifles used or exported by the Chinese military have threaded muzzles.  The non-threaded models are commercial models for the US market only.  I don't know where you got your info but your wrong.  The type 56 either used  an early AK47 bayonet that uses the little "fangs" on the fsb to lug to or the folder bayonet everybody likes.  The muzzles could be found with muzzle nuts over threads or slant comps.

As with everything Chinese, there's a lot of exceptions to the rules with the Kalashnikovs (and the same applies to many countries that made the rifle).  You'll notice a lot of "most," "some," and "almost all" words when describing the Type 56 as the rules sometimes went out the window.

However, practically all the military Chinese Type 56 rifles have no threaded muzzle (with the exception of the very early ones)  The threaded muzzle is found on some export versions (some military and most commercially sold semi-autos).  

The older milled receiver variants with the spike bayonet have threaded muzzles.  The later stamped receiver variants with the spike bayonet almost never had a threaded muzzles.  However, almost all the later imported commercial semi-autos with the spike bayonet have threaded muzzles.

I have hundreds of photos of various Chinese rifles and wish I could throw them all on here but just too many.  However, here's some that can serve as food for thought regarding your project:

Type 56 with full buttstock/milled receiver/spike bayonet - threaded muzzle:



Type 56 with full buttstock/milled receiver (commonly called the "M22" for export purposes) - threaded muzzle:



Type 56 with underfolding buttstock/milled receiver - no threaded muzzle:



Type 56 with full buttstock/stamped receiver/spike bayonet - no threaded muzzle:



Type 56 with full buttstock/stamped receiver/spike bayonet (export version/markings) - threaded muzzle:


Type 56 with underfolding buttstock/stamped receiver - no threaded muzzle:


Type 56 with side-folding buttstock/stamped receiver (with export version/markings) - threaded muzzle:




Type 56 with side-folding buttstock/stamped receiver (with export version/markings) - no threaded muzzle:


Type 56 with side-folding buttstock/stamped receiver - no threaded muzzle:

Over half your photos show muzzle nuts.  I might be wrong that ALL of them have threaded muzzles, but your still mistaking a muzzle nut for no threads.

I see what your saying now.

I've often thought that the Chinese might have been advised by the engineers at FoMoCo. Just as FoMoCo rarely made the exact same vehicle for an entire year, the Chinese seem to have made a bewildering number of variations of the AK.

China will make just about whatever anyone wants.  Check out these samples that a Chinese representative showed some Italian gunbrokers that had their mulit-million dollar arms deal for Libya get nixed (the Libyan buyers requested to have a grip like the Romanian underfolders had):




And just for folks that have argued Polytech never imported a commercial, semi-automatic variant that had a milled receiver and spike bayonet, here's a oddball that seemingly kind of got through:
