Ok, so I’ve installed this outer barrel:
Size: (L) 35cm
Female/Male End Threads: 14mm
Outer Barrel Dimension: 19mm
Inner Diameter: 9.6mm
And this inner barrel:
Material: Alloy metal (Inner barrel), Plastic (TPC)
Inner Diameter: 7.4mm
Size: 27.5cm, 29cm, 33.5cm, 40cm, 47.5cm
into my Gen8 M4.
I suppose the recommended DK J8S hopup won’t work now, because the barrel sizes are different.
Which hopup should I get?
