My palm is less than 10 cm, small hands. 2 MOA at 150 metres would be 87 mm.
I generally can shoot better, but there's a structural problem with the Kalashnikov action and its magazine; the split group/2-group tendency (which was caused by the staggered feed magazine, where the bolt carrier would tilt to its sides depending on which side the next cartridge in the magazine is seated) of the original AK-47 and the reverse-engineered Finnish rifles was eliminated by Valmet with the 76 model bolt carrier with a different geometry (flat instead of round underside; same geometry was applied to the M92S/95), but the problem with the last round, thus empty magazine not exerting pressure on the bottom of the bolt carrier unlike when there are rounds left in the magazine, has not been entirely eliminated, and this causes the last round to hit slightly apart from the other grouping. Generally if there's a dummy or a to-be-unfired round as last in the magazine, the M92S I've got can do around 1 MOA with Sako ammo, but if the magazine is shot empty, the last round will spoil the grouping. Neither in the Russian, Finnish nor Chinese magazines would the follower rise high enough to prevent this.
Valmet managed to eliminate the issue better in the .223/5.56 rifles, where the Valmet magazine feed lip geometry was copied from the Colt AR-15/M16 magazines (and with an empty magazine the follower exerts similar pressure on the bolt carrier as a round left in the magazine would, as the follower rises all the way up to the feed lips), but only in the milled receiver rifles, where the magazine would seat tightly enough to eliminate the sideways wobble. Galil also plays around this issue with a similar Colt-derived geometry.
The interesting thing with the M92S is that it shoots consistently with not only the Finnish ammunition, but also with Barnaul, Geco, PMC and PPU, although Sako factory ammunition produces the best results. Fellow reservists consider Geco to be the worst ammunition in non-Finnish Kalashnikovs, but for some reason the M92S handles it pretty well, much better than Sellier, which is by far the worst in the M92S.
Sako hasn't been producing the Kalashnikov type semi-automatics after FDF ceased further orders by the end of 1998, but until then the yearly production was about 10 000 rifles a year. Valmet could do over 30 000 a year (they bargained with the Saudi negotiations that they could supply the 100 000 rifles within 3 years), but the Valmet Tourula factory was run down some years after its merger by Sako, as the all-manual machinery was thoroughly outdated, and all remaining production would be transferred to the Sako Riihimäki factory (where the RK production lines were obsolescent as well). Because of no further FDF orders, the US assault weapons ban and international military markets being overloaded with Cold War surplus, Sako chose to close the production after 1998.
