Here is the latest product news from da Vinci Airsoft:

Dear Sir

This is da Vinci Airsoft.
We have a new item , 01 Raizen Inner Barrel for VFC & LAYLAX SIG M17.
It has a unique barrel design, so different from Tokyo Marui.
When we did some FPS tests, only 6.01 dia. get high score so lined up is only 01.

01 Raizen material is high quality stainless steel (SUS304) made in Japan.
Using Japanese CNC to cut, polishing each barrel by craftman’s hand
