I need some expert raptor help. I bought a raptor as part of a bundle of stuff and it came with the parts in a bag. Could someone look at the parts in the picture attached and see a) if they are all there and b) take me step by step or refer me to a step by step on how to reassemble this gun. I am 30 years old and haven't played for about 10 years, I am started to get back into it again, so I have to relearn everything. Be gentle.
