Review on Enhance Your Engine Performance with Red Line RED80312 Assembly Lube - 4 oz. by David Silva

I recently tried this on the outside of the bolt carrier and cam pin on my AR15 at the recommendation of a local friend. It's not even NLGI #1 thick by my reckoning and it works very well as it's not very thick or sticky like any other lube I've used. The extremely light coating on the sides of the gas key, the 4 rails of the bolt carrier and the underside where the hammer moves immediately and slightly noticeably improved the smoothness of my worn out LMT frame. This improvement was noticeable over FireClean, which is still the gentlest LIQUID lubricant I've ever used on a firearm. The frame was well lubed with FC before I removed it and applied this lube. A little goes VERY far and I only used the tip of the cue to apply it. It's also MUCH cheaper than pretty much any other "gun grease". Simply excellent. I am very satisfied and will update if there are any issues (I doubt they will).
