My apologies for doing an addendum but I was rushing out home for the express bus so...A few other questions.
Is there a new grenade launcher? I don't imagine the old ones will be compatible.
It looks like there is only a single hole in the front for attaching the sling. Is this a new single point sling design? I could not see clearly in other photos.
Since the new rifles still have full auto, what would the point of IAR be? I imagine LMG/SAW is much more useful (defined as something with belt feed/QC barrel for sustained fire application). I would hope that new fabrication techniques could be applied to new SAW/LMG.
QLG-10A, as far as my observation goes, there're 2 attachment points to the rifle: the barrel clamp and one point on the unit itself. The barrel clamp seems to be removeable (there's an allen key screw on the base) so it should be just a matter of switching out the part; the problem is the barrel as it is designed to tug nicely with the current QBZ-95-1 handguard, so the only way to make it easier for modification is to make a modified QD-capable firing mechanism for the QLG-10A that gives enough clearance for the bottom rail for the barrel yet does its job.
Or, they do a "QLG-10B" (hey ain't nobody gonna quote me on this one! I merely give that a logical stretch, I could be wrong on this one!), which totally engineered to satisfy the possibility/constraints provided by the bottom rail (yay), no barral clamp so to let it remain free-float (yay), in this case, it could be a modification from the QLG-10 (designed to fit the QBZ-95), the front handguard should be long enough to cover most of the launcher, if the "normal" handguard (we only see the carbine version so far) doesn't have that long a bottom rail, they can always have a "grenadier" handguard...the problem is that much trouble won't they do it like AG36 instead?
As for IAR question...we may look at the USMC with their M27 IAR for clues. Besides from their excuse to introduce HK416 into the arsenal, for them the IAR isn't to replace the SAW but to supplement it; IAR has the advantage to make the squad SAW gunner indistinguishable from the rest of the squad at range, and he does his job by burst fire pinpoint suppression instead of dumping it downrange. Also, depending on the interchangeability of magazines between QBZ-95 series and the new series (we know via patent document that the new magazine is interchangeable for all), the ammo drum for QBB-95-1 can be carried forward to the new gun, will need a long heavy barrel for that role of course. That is, if that's what they'd do and not adopting a new belt-fed SAW.
