Have a 416 receiver set. I used it for about 1.5 years before my gearbox inside broke, then i built a mk18 and stopped using the 416 body. The pink stuff is just dust and wipes off, so its not permanant🤣
There is a small crack in the front of the magwell, but it does not affect performance at all. It cracked before i ever used it, during assembly, and after 1.5 years of use it never expanded. If you have any questions or offers let me know! Sms 0683221892- stu
