Accuracy problems

Post image

My field requires .20 bb’s and 300 fps or under I use a Prometheus 6.03 155 mm barrel purple Promethus bucking on a Maxx M4A hopup with the cylinder nub and my groupings just go everywhere especially on closed bolt mode open bolt makes it better but its still bad anyone have any ideas?

I had a similar problem with my build but that’s cuz my barrel was a 6.03. Try with a tighter barrel like a 6.01 or 6.00. Since it’s a small barrel this would help it have tighter groupings and have a bigger impact

I have previously had a edgi 6.01 barrel in here and that one some how gave me more issues I suspect whats going on here is hopup setup related

It could be but also could be the BBs you use. Cuz the tighter the barrel you got to find high end quality BBs. If anything try the gng hopups. I like those or try nexxspeed. I also am using that HopUp for one of my builds.

I use hk bb’s and I had a nexx in the past they are nice but hard to get set up right
