I am certainly no expert by any means, however, if you are investing that much money in a JAE stock, invest a much lesser amount in accuracy to go with it. The purpose of unitizing the gas cylinder is to strengthen/stiffen the barrel to stabilize it under load, thus aiding in tightening groups.
The JAE barrel tensioner works with either standard or unitized gas cylinder assemblies. However, best results are obtained with a unitized system since tensioning alone will not prevent the barrel band from moving about, which is detrimental to accuracy. The advantage of the tensioner is that it allows adjustment to the amount of tension being applied to the barrel. Some rifles require more than others for best accuracy, etc.
