One thing I liked with the gevarm .22 is the open bolt meaning you can have the weapon cocked and have the magazine in your hand, very quiet to slide the magazine home when going to shoot, and also very easy and quiet to make safe.

I filed a second notch in the mag to hold the mag below the point the bolt would strip a round out.
At first a few extra bunnys lived as I forgot to put the mag the rest of the way in but I learnt.
Still, as it's hard to buy a new gervarm and the mags tend to be worn on what you can get second hand....
