Just as the title says MCX up for sale decided I wanted to swap back to an actual m4. Stock internally besides a krytac motor, deans connection and a lonex inner barrel. Original barrel ended up gunking up and could not be saved. Just dropped a fresh m120 spring in for field usage. Feels great just wanting the new cm4 erg. Grip, sight, and suppressor not included. Oem box is. Battery space is tight. I can sell some lipos that fit for an additional fees. PayPal only, message with any questions. Can provide more photos. Thanks!
