It's more than likely a barrel/bucking/hop up issue.

My CM16 from the factory had a slight right curve due to the bucking being twisted inside of the hop up unit.  This meant the nub that protruded down wasn't quite centered in the barrel.  I took the hop up unit, bucking and barrel apart, reassembled them (making sure the nub was straight this time) and the issue went away.

Hopefully this helps.

Alright, i just disassembled and reassembled the barrel and bucking. It's very loose and slides easy. Any way to get it to stay in one spot? I'll post again if that helps, either way i agree that it must be a crooked bucking or something. Ill test fire it and get back to you. thx

If it's loose in the hopup chamber IE it's sliding too easily there you can add just a little wrap of teflon tape around the bucking being careful not to cover the area where the nub/arm pushes down on the hopup bucking and also missing the area where the C-clip attaches the whole thing to the barrel. That will make the fit a bit more snug which should also help with air seal in that area.

Before putting it all back in the gun though take the assembled barrel/hopup look through the hopup end with the hopup fully engaged and make sure the nub on the bucking is perfectly centered in the barrel. Aside from a bad bucking, or torn bucking that should solve any problems with it going one way or the other.

Another thing to watch for is a problem with the outer barrel being bent which can cause all sorts of these issues, or some defect in the inner barrel, or some BB residue in the inner barrel. None of which is nearly as common as the bucking being misaligned so I would certainly start there.

After some test firing, it seems to just kick around the bucking. After pulling it out a second time to apply teflon tape, i saw it had a tear, not sure if I did that or what but im going to try that Modify Flat hop bucking and nub anyway.   Thx guys

A tear in the bucking will cause all sorts of trouble. The modify bucking should serve you well though
