Help on how to get better accuracy

[straffham]

You could try just the new bucking, that alone may make a world of difference, before splashing out on a new barrel, nothing to lose at any rate.

try heavier ammo first. don't change anything else, just put 0.25g BBs in it and notice the difference immediately.

0.20g ammo is frankly rubbish and only useful for chrono and extreme CQB where accuracy past 20' doesn't matter.
