I've searched around and I'm pretty sure that the correct sizes are 10mm, 6mm, and 3mm. I'm ordering some goods off LC Engineering and saw that they have a vacuum line kit containing 4mm, 6mm and 8mm and states it's for the 22re as well. Has anyone ordered this from them? Will the 4mm be too big, or should I just stick with the 3mm?
