Hello felas! I have some questions about hpa guns. I want my gun to be DMR with high velocity (not less than 450fps, but not more than 600 - to ), highly accurate and semi-only. I chose MAncraft, because it's mechanic only, only semi and available in europe. So, here are my questions: 1) Flat hop, Rhop and so, do they perform the same way as on AEGs? 2) What type of Barrel? Tight bore 6,00/6,01/6,03/6,04 or wide bore 6,23? 3) What about barrel lenght? 4) Ideal BB weight? I suppose it should be 0.4g Thanks for your replies!
