>Russian MIC isn't exactly transparent
True, it's often intentionally opaque to a counterproductive extent.
>pic related
That's cool, thanks. Yeah, that looks like one hell of a slug.
>tungsten-core 9x19mm 7N31M is a thing
9mm PBP exists specifically because PP2000 was a PDW project in the vein of P90 and MP7, with GSh-18 as companion pistol. It's still billed as such on RosOboronExport site. Defeating (then-)current issue body armor was a core requirement, but the developers didn't have time or resources to invest into developing a whole new cartridge caliber and didn't want to export secret squirrel 9*21 ammo, so they just overbuilt 9*19 to hell, way beyond any reasonable relation to SAAMI spec. 7n21\31 are known to shatter Glock frames with very low round counts, a handful of mags basically.
>why not an improved 7N37?
Why not, indeed. Just enlarging the penetrator and not telling anyone except end-users about it is pretty on-brand for (post-)soviet MIC. The new and improved post-'23 AK-12 is still an AK-12, for example, even though it's about half parts-compatible with the previous iteration.
>Israelis developed a technology called "LIBA"
If there's anything you can trust the jews on, it's inventing shit to cover or save their own asses.
>one plate ate quite a few 5.45x39 7N39
Well, yeah, it's not really supposed to defeat Br5 or equivalent armor, no 5.45 cartridges are expected to do that. It obviously lacks mass, and similarly enlarging the penetrator would run into pressure\velocity issues, I guess. Also, it would be pretty expensive upgrade for an already expensive assault rifle round, where it's harder to justify than for DMR rounds.
>On dirt bikes or golf carts?
Depends on how well the boring of Chukotka-Alaska tunnel goes, maybe by trucks even. How would you like a 14,5" billet AR with 2-stage trigger, adjustable gas block and forged, chromed barrel?
