Hello everyone. It has been very hard to find any varget lately so when Midway got some I jumped on it. However, the bottles I received did not have a seal on them when i uncapped them. I was alarmed and i called the sierra tech line and I was informed that they had to change the manufacturer of the bottles and that they were no longer sealed from the factory. The tech assured me that the product was fine. I just thought that I would share this info just in case you were wondering, as I was, as to the integrity of the product.
