da Vinci Airsoft have added some new barrels to their inventory:
Today we add Guren "2" to our lined up.
Guren 2 has tapered end to make good airflow.
So compared to Guren 1 , FPS is about 10 % better than Guren 1.
(But the total cost is more expensive than "Guren1")So if you want to exchange the cheaper barrel but keep the quality, recommend "1"
If you want to gain FPS and accuracy, please choose "2".Guren 2
128mm / 3,600 Yen
141mm / 3,800 Yen
208mm / 4,200 Yen
229mm / 4,200 Yen
247mm / 4,200 Yen
