Just wondering if anyone has upgraded this with a tight bow barrel and new bucking. Also, what BBs have you been able to hop with this?

I’ve got one here across the pond and I get roughly 1.5 mags (75 rounds)with the 50 round gas mag. The acetech brighter c works best as it’s light. Heavier tracer units cause the slide to bind, but the brighter c is golden. Acetech brighter c. Small and light and works great Has anyone who owns one upgraded the barrel and bucking at all and if so, what did you use?
