Hi folks, haven't been here in a long time. Just wondering if anyone has bought the new Umarex CO2 MP40. I acquired one last week but ran into problems with the fixed hop/BB holder in the mag. It seems the hop imparts some back spin on the BB's and they fly sharply upwards after around 50 to 60 feet of travel. I tried another guy's magazine and his didn't cause the same effect, though the groupings did seem to be a bit loose. Just wanted to compare experiences with anyone who has bought one.

What bb are you using? You might try heavier BB. Basically the hop-up is too tight for the light bb. However - can be too tight for any bb weight.
