I have greatly enjoyed the experience using my Carbon upper. The build quality is superb and the fitment is exactly as described even though I’m not using the proper combat machine lower.
This upper was a real head turner at the feild and had people questioning why it was outranging them. Paired with the AirTac F2 this build was a formidable fast replica that has become one of the favourites of my collection.

Many of my buddies use an Airtac upper and it feel nice to use. This paired with a slightly weighted lower is amazing. I’d recommend getting one.

I own 3 155mm and 1 128mm, I absolutely love these uppers. Their performance, durability, light weight, and appearance are all stunning. I recommend these uppers to everyone. My tournament setup of choice every time without question.
