Mr. C's Super Sekrit Gun Oil is a special blend of synthetic and petroleum products, along with some special secret "herbs and spices" that produces an extremely smooth low friction sliding action. A very small amount goes a long way, and you can actually feel the added smoothness in many cases. I use it myself, and on my own guns I can tell the difference.

It's hard to judge the bottle size from the picture, but it is a 1/2 oz. bottle, and contains approximately 1/2 oz. of oil. The bottle measures just over 3" high, and is just under 1" in diameter. One bottle should last a long time.
