Fx Carbon Fiber Sleeve Problems

Well, FYI, I just received a message from seller, that they met such issue in the past. They contacted FX directly and statement of FX is that it does not hurt performance of a gun.

So, it's not nice, it does not look professionally (personally, if I would produce such part, I would not dare to send it to the world), but it is as it is...

Honestly, I'd expect a different kind of quality control for guns which cost 2000 $...
