I recently picked up a used CYMA AK 104. It shoots great, strong and long. The only issue I have is that it shoots low/left. It's got a TBB and different bucking in it. Upped spring as well. The rest is stock as far as I know. The front sight is not adjustable left right like an AK would be, with the press. Is there any way of adjusting things (inner barrel, etc...) to more 'center' the shots?
