I use this for airsoft gas blowback guns, as a lubricant and sealing, and it certainly works extremely well. My bolt ran as smoothly as silk after applying a few drops. The oil itself is relatively inexpensive, and shipping was extremely quick and cheap. Definitely something I will buy more of at a later date.
I use this Silicone Shock Oil in my Airsoft guns works fine and is cheaper than airsoft silicone lubes.
