I have the Evo rifle in Fl. I think the ergonomics and the trigger on the Scorpion sucks even with the HB spring kit modification and/or shoe modification. The ergonomics are not the best on the pistol grip or on the design of the safety levers. Fortunately, there are good aftermarket replacements. The standard CZ mags also suck, because the plastic feed lips break now there are lots of better aftermarket mag options--magpul, palmetto state armory etc. Both of these type mags are far better than the CZ mags. However, what pisses me off is that you should not have to spend more money on top of the price to achieve a good trigger, better ergonomics and a decent quality mags. The sling attachment point on the rile did not accommodate a circular push in sling connector and only an HB type connector, so I added the aftermarket fix for that. I am planning on doing the ShootingSight just released new two stage trigger for the Scorpion.It is available as a parts kit or drop in assembly. If the trigger on the micro is the same as on the rifle or basic pistol, it has to go. I also think that both the Scorpion rifle, pistol and Evo are overpriced for what you get. The rifle is very accurate, so that is a big positive. All being said, inspite of the extra money I spent on it, I would not sell it. The recently released Gen 2 Palmetto State Armory AK-V pistol, which I keep in Fl is in my opinion a much better option for about 1/3 less on the price.
