So, I was just adjusting my hop-up in the backyard when I noticed one of the screws fell out. Damn I thought, I better make sure the other screw is in so I thought I tightened it. Fired off a few more rounds and went to adjust and realized ALL screws for the hop up were gone! Does anyone know where I can find replacements? Is it a Bunnings job or do I have to buy a new hop up?
