"Gregor"3 cm at 50 meter is 2.06264781495325 MoA. That seems closer to 2 MoA than to 3 to me...
1,5 cm is half of 3 cm so it should be 1 MoA, right? I have tested a wide variety of airguns. I am sure a lot of people have tested even more. Regardless to what is said on the internet, airguns that consistently shoot 1 MoA or even less are extremely rare (I have not seen one in person yet). Most very accurate and expensive airguns will shoot between 1 - 2 MoA (maybe I'm not a good enough shooter). This is information without exaggeration. That means that with Huben you get a high efficient regulated airgun with power capabilities as no other, semi auto with standard high end airgun accuracy. Lets not forget that low power very accurate airgun is useless at 100m because the wind, and the drop curve, and the drag of the pellet. I do think however that Huben could be even more accurate if it did not shoot out of the magazine but rather feed the pellet / bullet in the barrel. But that is not possible with this design.
