Just today I bought an electric Umarex HK P30. I put the batteries in as the manual showed(and have tried every other orientation possible as well), and loaded it with one bb to test, but nothing happens when I fire it. No shot, no motor sound, nothing except a squeaking sound. I tried to disassemble it with a video but the orange tip seems to be fused to the gun, which prevents me from disassembling it any further than taking off the slide. I’m brand new to air soft as you can probably tell, and this is my first gun. Any help would be greatly appreciated! It might be a user error as I have little idea what’s going on here.
