QBZ-191 service rifle family

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.

You can technically fire a lot of smaller cal rounds using a higher cal rifle. With 5.56 and 5.8 being so close in size, you might get away with out too much casing deformation, which is the main issue when doing this and would typically result in a failure to extract and you have to field strip your rifle to extract the spent casing to load a fresh one.

But you will probably still suffer from very low chamber pressure (which again might result in malfunctions with a gas piston design) and maybe even bullet tumble if 556 is too small to properly engage the rifling of a 5.8 gun.

And of course, you are going to have a lot of issues trying to use M4 mags in a Type95.

If you need to load up Type95 mags with 556 first before you can shoot it, you are far better off taking the mags and rifles off of dead enemies and using them rather than trying to using captured 556 in your Type95.

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

Yeah, something like that. I should put the M4A1 Block 1 and 2 as my example.

There are some major differences between M4A1 block 1 and 2, and what you described in terms of adopting the QBU191's FF MLOK handguard for QBZ-191 actually would look externally more like the URG-I than Block 1 or Block 2.

The length of the handguard is what needs to be clarified, which would determine how complex such an upgrade would be.

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

In the first picture, is he using power because the gun is slippery ?

Sweat, your hands sweat a lot when you’re nervous and that can make things very slippery (depending on the material of the grip). Case in point one thing I don’t like about glock 17 is that it’s grip and plastic frame gets really slippery when my hands sweat to the point that it makes it a bit difficult to control the recoil. HK P30L does not have the same problem, since it’s grips are modified to increase friction.

Wearing gloves can help to increase friction but that is at the cost of losing your sensitivity on trigger pull, which can reduce your accuracy by quite a bit especially on pistols. Your tactile perception suffers a lot when the glove is in the way and it really matters for shooting.

Since these are pictures from a shooting competition in Russia, it makes sense for PLA shooters to use gym powder to help maintain their accuracy and control of their gun while under stressful situations. I’d do the same too if I were them, that’s a smart move given the context.

This may also tell us that the pistol grip on QBZ191 is not completely rubberized, so it can get slippery when your hands are sweaty. Some people do not like rubberized grips as it can get caught on random stuff and dirt, I don’t mind it but I can imagine why some people do not like it especially given a military context.

Honestly could just be the guy wanted more grip than usual. Nothing says that it's slippery. It's the same idea of putting a grip on the AR-15 to reduce the already low recoil.

DBP191 ammo comes in these types of packaging.



The plastic box on the right should be carrying 7.62x51mm sniper ammo, the left are 30 round DBP191 rounds.

So close but still nothing on the ballistics of the new ammo.

Just a correction, but the plastic box is labeled 5.8mm
