So I just got an Echo 1 Platinum M4 for Christmas and I went to shoot it for the first time. After I was done, I went to take the battery out and it was stuck. I kept trying and ended up just taking the stock off. When the stock came off, the wires unplugged from the gearbox. I need to take off the buffer tube but the buffer tube screw is extremely tight and everything we try it just keeps getting more and more stripped. We have tried everything and nothing is working, so please help. Thank you!
