Here is the math. The lvoa is 650, the titan gate is 200, The lonex A1 motor is 110, the gearbox shell, 13:1 shs gear, nozzle, cylinder, shs high speed piston, piston head and some small stuff I’ll say 300. The magpul stock is about 60, I have been invest over 1300 in this gun. Now I’m asking 750. Not willing to swap.
