The gas system of the RIA VRBP100 is not necessarily new, but it is slightly different from other more common designs people are familiar with. I personally am not familiar with too many semi auto shotgun gas system designs, but I know that this shotgun gas system is relatively unique to Turkish shotgun designs. However, it is basically akin to a short stroke gas system you seem piston operated rifles. I have had a little bit of an issue with this shotgun gas system during the break-in period. I am going to go over this issue and discuss how the system works and what might be happening internally to cause these issues.
