What SEA countries importing them? I am assuming for their armed forces as none in SEA that common citizen is allowed to have a rifle like Type-81

Most of the Type-81 I’ve seen in media are from Bangladesh (supposed to be licensed production), Sri Lanka, and Myanmar ethnic militias (Kokang, Wa State, Arakan, Kachin). Supposedly the rebel groups can produce locally, but probably still need (or is more economical to get) parts from China.

I don’t have the source, but this was a very early rumour after the Type-95 was introduced publicly (HK handover time). I remember reading around that time as well, but it was never backed up and didn’t seem like a useful capability anyway. Like posted above, if PLA is scrounging around for NATO 5.56, things have gone horribly wrong.

I've seen people saying that 5.8mm is designed to be compatible with 5.56mm in emergency, I am almost 100% certain that is a complete fabrication that originates from 地摊文学 (extremely unreliable sources). But since it's been around for so long you'd find a lot of sources referring to the same thing. Let me just say this, just because you see a lot of sources saying the same thing does not necessarily make it correct.

It is entirely possible to fire a 5.56mm bullet from a 5.8mm gun. The bullet will probably fit in and if you can close the bolt on the bullet and let the firing pin hit the primer, then it will ignite. But, this does not mean it is a viable thing to do. First, because the diameter of the bullet and the chamber does not match and will not create a perfect seal, the powder will not burn completely and your bullet will not go very far in an accurate manner, even if it shoots (you'll shoot most of the powder along with the bullet tip). Furthermore, the gun will not cycle properly and if you want to fire 5.56mm ammo in 5.8mm gun, it will be a bolt gun at best, and it will not fire every time. The final problem is that when the chamber is not sealed completely, the gas created by the burnt powder may not all be used to push the bullet head forward, it may exit from the weakest point in the casing and erupt the casing, making it stuck in the chamber, which can be extremely difficult to extract.

How do I know the above? From personal experience shooting a 5.56mm ammo in a 7.62mm gun. It was a stupid accident but it gave me some interesting insights on how this type of thing might work.

Now, if we are seriously talking about the viability of shooting 5.56 in 5.8 gun, you can probably do it and it will probably shoot. But, your gun will not cycle, and you may have to deal with erupted casing each time you fire. Furthermore, your bullet will not really go far since most of the powder will not be ignited. If the load in 5.56 ammo is hotter than what your 5.8mm chamber can handle, your gun will blow up in your face and shrapnel created in that may kill you.

So let me just say that 5.8mm rifles are not designed to be able to fire a 5.56 ammo under emergency situations.

Even guns that fire the same caliber like different ammo. 5.56 guns with different twist rates in their rifling perform significantly differently depending on the type of 5.56 ammo you fire, some like 55 grain tips, others like 62 grain tips. My G36's zeroing shifts by 3 inches above at 100 meter when I switch the brand of 5.56 ammo I fire. If you fire a 5.56mm bullet in a 5.8mm, it may fire, but it is not going to function in any meaningful manner.

I didn’t want to go too off topic, but I also remember reading something like the relatively poor performance of the original DBP87 round and original 95 could’ve been an related to compromises made to fire the smaller 5.56.

The rumour probably persisted because the DBP10 introduced with the 95-1 has performance more consistent with the original heavy 5.8mm. Logically, it implied the original 95 could work with a range of chamber pressures.

Doesn’t really matter though because like you said rumours aren’t facts. If 95 could reliably fire 5.56, then 97 export version wouldn’t exist.

Speaking of Burma rebels, they also are seen with 97 and the super rare 03. How long before we see 191 in the USWA parade?

New footage of the QBZ191 close to the end of the video the censor bar is much smaller while Im looking at full auto Im unable to calculate the rate per minute of this rifle.

I notice that the video thumbnail seems to show a shot that isn't in the video, shows one person carrying a QBU-191.
Interesting that it's not part of the video itself... but perhaps for future content

I've been wondering for a while now. Would a handguard like the QBU 191 work on the standard QBZ 191? Does having a short gas block in the middle of such a handguard cause issues?

Do you mean a free floated handguard of equal length to a QBU-191's handguard?

Naturally you'd need to change the barrel nut on the QBZ-191. That could be issued as part of an upgrade kit without much issue.

A QBU-91 length handguard on QBZ-191 will naturally be longer than the QBZ-191s gas block as you correctly describe.
It shouldn't be much of an issue, if they are willing to accept that the gas block won't be adjustable on the fly.
The handguard length would however require the front part of the adjustment mechanism to be lowered or removed in some manner.
In practice, that would be done ideally at as low a level as possible. Either new gas block parts would have to be issued with the upgrade kit, or the adjustment mechanism has to be literally cut off at the armourer.

The M27 IAR has a handguard that is longer than its gas block.


Alternatively, they could pursue a handguard that is still free floated but the same length as the current handguard on QBZ-191, which won't have the gas block issues
