Boonie Posted April 8, 2022 Posted April 8, 2022 Posted this in the AAP-01 thread but thought I would ask the wider audience as well. Can anyone help me out? The hammer broke on my AAP (as usual I guess) so I have replaced it with the cow cow steel hammer, since then the gun has been acting odd. It will jam easily and runs on full auto no matter what I put the fire selector on, the bolt also stays open and gas escapes. I have stripped down, lubed nozzle, rubber, slide etc, replaced both the recoil (cow cow) and nozzle (Waldo) springs but still the same issue, this happens on my HPA and green gas. Any tips?
Guest Posted April 8, 2022 Posted April 8, 2022 Yup, you should have put either a full cow cow hammer assembly in, or just replaced the broken hammer with OEM. Mis-matched parts just don’t work in airsoft
