Actually, from my understanding, the phenomenon pvt13 is talking about is something completely different from barrel suck. Barrel suck was thought to be an issue arising from the piston of an AEG sucking air back in to the cylinder before the bb has time to reach the end of the barrel; what most people had failed to take into account is that with any barrel length available on the market, the bb simply leaves the barrel before barrel suck could become a factor. HOWEVER, in-barrel turbulence is a very real factor that is detrimental to both muzzle velocity and accuracy that arises from imperfections in the surface of the inner barrel.
