In order to understand the title, I previously wrote to customer service and asked whether the gearbox would fit into the Ares M249 without any problems. I was told that it would fit, unfortunately that's not quite the case and I have to make some changes before the gearbox fits on both M249 as well as the Gearbox That's why I only give it 2 stars because the customer service gave me bad advice and it's not financially worth sending the Gearbox back. I hope that they try to contact me to at least apologize
