i just want to know what is the purpose the the vents or ribs on a shotgun barrel? They dont seem to vent anything the barrel is just as hot when fired alot and they give no room for a heatshield.

Ventilated ribs also elevate your sight plane, giving you more than the reflective bbl surface (which often glares) as a bottom of your 'sight box'.

Vent ribs are worth the investment.
If you can see light anyplace between the top of the rib and the top of the bbl it would be considered a ventillated rib. I have a solid rib gun, but I haven't seen one made new in a while (at least on a pump - double's a different story).
