Not only am I a certified Gunsmith/Armorer I to have been around weapons ALL my life. I'm telling you from FIRST hand experience there is NO BETTER firearm lubricant in the known universe.
I know guys who have used and use it in current theater; Afghanistan.
If all you can do is reference what you have read please go to the website:

Scroll down to the third from the bottom entitled 'Afghan Eddie O'... These are the folk I personally know!
I have even had feedback from a close friend former Marine (OORAH!) who told me it makes him shoot better. As all the recoil is placed into the springs (semi-auto) and friction is lost from the equation...
In bolt-action firearms it decreases lock time...
Semi-autos run the way they should with a lightened trigger pull and smoother action...
In full auto firearms it will reliably increase cyclic rate!!!
I know the Navy SEALs use it and there is no outfit that puts a firearm through more torture than them (HOOYAH)!
Gun Butter does NOT attract dust, dirt, sand, or talcum powder
It stays where you put it. It eliminates corrosion. Doesn't allow fouling to stick. Kills rust. This lube does not freeze nor can you light it on fire! I wouldn't use any lube that catches fire, in a FIREARM (such as WD-40). CLP is making a pasty mess in Iraq and Afghanistan.
I guarantee if you use it as prescribed your cleaning supplies will change!!! And a 2/3oz bottle will last well over a year going to the range every weekend with three firearms
(ie: 870, AR-15, and 1911) So do the math...
If all you do is shoot your guns to make them go bang and don't care about the wear and tear, accuracy or functionality then by all means go the cheap route. But, if you rely on your firearm to bring home the bacon or cover your six or to protect your FAMILY...
THERE IS NO BETTER FIREARM LUBRICANT!!! PERIOD!
