4UAD Smart Airsoft has taken a VFC M110K1 gas blowback rifle and modified it to achieve an impressive shooting range of up to 80 metres. There have been a few issues encountered with the M110K1. One of the problems was a light strike on the hammer, which needed to be resolved. Additionally, the buffer tube on the M110K1 came off, requiring attention. There was also a need to increase the hop-up for better performance. A misaligned rail was another issue that needed to be addressed.

The modified rifle was tested at the Rhino Airsoft Field, where it was put through a range challenge. The overall feedback and conclusion from this experience will provide valuable insights into the performance and potential improvements for the M110K1.
