Awesome thanks for the information. They definitely seem like really fun plinkers.Reliability on them is excellent. You can change the speed of the bolt with just an Allen wrench. Accuracy is not that great and trigger is poor out of the box. Trigger spring upgrade kit from hk parts helps. Fun guns once the trigger is improved. I have 2 MP5s 22s, an hk 416 22 braced pistol, and used to have a colt m4 22 rifle.
They are all made in the same Walther factory and have the same trigger group, bolt, etc. all have been extremely reliable. Beretta arx 160 22, g36 22, and some others I can't remember have the same basic design and made in the same factory too. Not sure about the uzi 22 but maybe that one too.
