EMG F-1 Firearms BDR-15 3G AR15 Full Metal Airsoft AEG Training Rifle (Model: Black / Red / eSE)

"I got this gun over Christmas and it works fairly well. There were a few out of box issues to resolve but otherwise the gun works great. It makes a great gun for beginners, being a beginner myself. The only thing that I wish was more specified is how to get the orange tip off, I could just be an idiot and not know this stuff yet but I cannot find the right hex that fits in the pin that holds the tip on. I would like to get a tracer but I can't until i figure this out. A response would be super helpful.
