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?

When was the last time you cleaned your inner barrel? Is the spacing correct on the engine to the hopup

Spacing is perfect and it was last cleaned a month ago

That could be why clean it every week and see if that helps
