All I know is my MAK90 is an excellent shooter. A lot of folks will say the Chinese made some of the nicest AK variants out there. I'd have to agree with them as I've owned two and they both ran/run like silky-ass buttered goodness. Years ago a friend had a, what I believe was a Century-built WASR that had the worst trigger slap I've ever felt on any firearm. The fit and finish was shit. It ran though, and from what I remember the accuracy was about what you'd expect.
The saying that "the best Chinese knock off is their AK" is true. They are well put together, smooth, and function nicely.
other notoriously available AKs that can be bought off the shelf in MA:
Saigas: sporterized civilian export Soviet AKs- very nice firearms with good hammer forged barrels on Russian receivers. Conversions yield nice rifles, and if you are a cheap bastard, this route will yield you what you want for the price that you desire
Romanian WASR: Romanian civilian export rifle. Rough finishing, some older models can have sloppy triggers, but nothing that can't be fixed by a $25 fire control group and a retarded brain operating fumbling hands. FCG replacement is a PITA, but with any sort of motivation and resolve, you can do it no matter how stupid you are. Hammer forged romanian barrels on a real WASR. No mag well dimples- spot welded plates govern magazine placement. And Century Arms hogs out the mag well to fit double stack magazines. Check front sight post alignment to rear sight leaf before buying. If it lines up, you are fine.
People don't like the poor black oxide finish, the general shoddy machining from used rough romanian tooling, the magazine slop (inherent with the plate design), or the poor triggers. The latter can be fixed, as previously stated, and the former issues are personal preference. Not once will you hear of people saying that they don't work. Because they do. If you don't want a poorly finished AK, refinish it yourself or buy something else.
MAK-90's: previously covered in thread- they are nice but sometimes come with a "butthole" (thumbhole) stock. Easily replaced- unless you have a slant cut receiver, then your options are limited.
CAI/Intrac Maadi AKs - post ban imports, nice rifles. Egyptian markings in arabic sometimes can be found on them. Designed for a double stack mag like a MAK so they run solid out of the door of the shop without any worry of FCG or mag well modifications.
Pre-Ban AKs: Polytechs and Norincos (chinese AK variants) comprise most of these, unless they are Mitchell Arms Yugoslav imports or Hungarian imports (Kassnar SA-85s) or preban Egyptian Maadi AKs (Steyer imports). All of these are nice rifles. They also demand more money due to their limited volume stateside.
I'll add more to this as I see time, but I've posted all of this info countless times on this forum. I'll just watch people add their experiences. If you don't see me ripping people's BS to shreds, then it's probably correct. Everyone has different experiences with different rifles. I'll only police blatant lies or "my shit is the best shit" posts.
I may get into
country-of-origin comparisons, why rifles are the way they are (AMD-65's were meant to be shot out of tank gunner slots, Yugo m70's are the way they are due to grenade launching and chromium shortages in the lands that those Serbs live on, etc) but it's all old had shit that doesn't really matter much to someone who is about to post "what is the best AK?" If those questions or topics pop up, I'll input what I know.
