Here is my tippmann m4 completely customized internally and externally. Externally I have a magpul ctr stock and noveskey nsr rail, I have also added on the cqb length and a noveskey amp. Internally it's set to hpa (I will send co2 parts as well) and its buffer tube is modded so it shoots roughly around 28 rps. On top of this I've put a shapeways 3D printed hopup nub in and upgraded the inner barrel. If wanted I will also throw in a sight mark redot for 50$. THIS PACKAGE COMES WITH A NINJA LINE FOR THE GUN BUT NO TANK
