Up for sale is my custom built C7E. This is based off the rifle used by the character Jackal from Rainbow Six Siege. The rails are 3d printed from PETG which is a relatively strong material. As long as you don't throw it against a tree or drop it 24/7, it'll last for awhile. External parts: A&K body $50 UKSR stock $80 M16 outer barrel $35 C7NLD rail segment $100 Red dot $20 Foregrip $10 Internal parts: Lonex gb shell $50 Lonex cylinder $16 Matrix padded cylinder head $15 Mushroom piston head $15 Shs metal tooth metal piston $15 400fps spring $10 Baal high torque gearset $40 Krytac 30k high torque motor $60 Madbull extreme hopup unit $30 Maple leaf AST 75 bucking $10 Maple leaf Omega nub $6 Just in parts alone the price is well below what it should be, so no I won't accept lower offers. Only trades would be for rare/oddball stuff. Gentex SPH4 helmet, VFC 417, stuff like that. Shipping is going to be about $25 since this a relatively long gun. Feel free to message me about any questions
