The M92S is the semiautomatic civilian version of the Finnish military rk95 rifle. The rk95 was intended to be a modernization of the Finnish AK platform, but it fell victim to military funding cuts as a result of the collapse of the Soviet Union. Only a small number were procured by the Finnish Defense Forces, and Sako only made about 2500 of the semiautomatic model for civilian and reservist use.
The M92 uses a brand new milled receiver design and includes a reinforced dust cover with rear aperture sight, a gas cutoff for rifle grenades (albeit never used), and mounting points for an optics siderail. The military rk95s all had sidefolding stocks, but the civilian model got a fixed stock as the folder would have made it much harder to register and own in Finland at the time.
These rifles, along with all the other Valmet factory semiauto rifles, just recently became importable thanks to the efforts of Postrock, of Garden City Kansas.

Recently https://www.armyrecognition.com/news/army-news/2026/hicar-ussocom-m4a1-82000-psi-556mm-upgrade U.S. Special Operations Command launched Hypervelocity Improved Capability Assault Rifle (HICAR). Apparently they found XM7 lacking for their purposes, so they elected different approach, namely: crafting high-pressure 5,56 x 45 cartridge paired with new upper for M4A1 carbine, able to hold said pressure. Said new cartridge would have pressure at least 82000 compared to 62000 of existing M4A1 (more than 30% increase). Without doubt such weapon would be shorter than mentioned XM7, but I am wondering what would happen if, say allied HK416-totting special forces operators would bring such ammunition from unconscious users of higher-pressure-M4A1 and try to use it in their own weapon?
Nothing good.
Just on principle alone, I’d ban this entire idea from ever being put on issue.
Good God above, we had enough trouble with the transition to M855 from M193, and that was perfectly safe to fire. You have no idea how many idjit staff types there were who thought the two rounds were interchangeable, and we’d be given M193 to zero and qualify M16A2 rifles with, only to have abysmal scores result due to “reasons”. Same thing happened in the other direction, as well…
You want higher pressure rounds? Make a different cartridge that doesn’t fit into earlier weapons that aren’t set up for those pressures…
