After the lubricant arrived, I went to the range and put it to the test. No odors or noticeable fumes came from the product. The lubricant is quite good although does not compare to higher end lubricants like Hornady. This is a suitable lubricant for intricate areas where a bolt carrier meets the BCG. I should mention two things: Fouling. The lubricant does not prevent carbon build up, so this is more for components that won't be exposed to prolonged fire where carbon deposits are heavier. It is a lubricant only after all. In the cold, the viscosity was somewhat higher. Once the gun became hot, the lubricant dripped like hot oil off of a spoon. I would suggest this as a last resort, when you truly need lubricative properties over a general CLP. Second point: Viscosity. I already mentioned how it runs, but this is a point I should expand upon. Cold, arid climates should use dry-oil sprays, like Ballistol. Hot, humid climates should use grease. A regular oil has no place in firearms, really. A runny oil will not suit well when a rifle is stored; leading to oil runs and trickles down towards gravity embrace. This being said, I do believe this should be used in addition to dry-oil spray, CLP, or grease. Spreading this on high friction areas, in addition to the aforementioned suggestions, the coefficient of friction will be heavily negated. I ran experiments on separate uppers. Same ammo type, same barrel length and gas tube length/pressue, as well as same BCG. I ran one upper with the lubricant only. One with grease and the lubricant. One with CLP and lubricant. One with Ballistol and lubricant. In my arid, cold climate, the Ballistol and lubricant ran flawlessly. The fouling was noticeable, although the unit didn't jam at all. Second, the CLP and lubricant ran well. After 400 rounds, the bcg became sluggish due to the CLP running down on the slower and leaving room for fouling. The worst was the lubricant only. I had a double-feed which was due to fouling on the bcg rails. Enough carbon accrued to measure out to 0.008g of fouling after scraping the surface with a polymer-type card, then drawing the oil from the scrapings. I imagine in Florida, or the Southern states when it gets hot, grease and lubricant would be a perfect combination. Be smart. Use different combinations for different climates.
