i have a we dragon and i was looking to od it from its stock form to a race gun. i would like to keep the original slide and frame if possible, due its design,the slide looks race gun-ish already. what internals do i need? i already bought an aip hopup for it,so if thats a good referance for brand parts, there you go. please if anyone can help me with this build id greatly apreciate it. im looking for faster cycling, lighter trigger pull and so on. im open to any advice.
