Alright so I recently picked up a Billy wing'd nt11 and was having some issues with it chopping (marb to be specific). I was looking on here and found a thread that stated putting an o-ring (not sure on the exact size) on the green bolt flow insert would reduce chops and allow the gun to shoot paint as brittle as ultra evil with little or no breaks.
Since my gun was billy wing'd I was under impression that the bolt flow insert was one of the pieces he mods and was not supposed to be messed with. My question is do I go ahead and remove the modded bolt flow insert and put a o-ring on it? Or do I remove the modded insert completely and put the green one back in along with the o-ring around it?
Thanks and any advice is gladly appreciated.
