Man you are correct; the one thing an AR platform DOESNT like is going dry!!! That’s pure unadulterated phooey. They are designed to be scuba’d up and swam with and the worst environment for them is the sandbox when they overheat with no lube.
He's wrong, you're wrong, and every other retard that parrots this "run the AR wet" bullcrap is wrong.

The case mouth pressure and resulting bolt force were measured for M855 and M855A1 cartridges as a function of the level of lubrication in a modified M16. The research found that the level of lubrication on the ammunition, and specifically the lubrication between the cartridge and the chamber of the weapon, greatly changes the level of force on the bolt face. The average bolt force difference between the conditions of heavy and normal lubrication was found to be 3000 lb. This force has a linear correlation to the pressure of the cartridge case and reaches a peak well before the unlocking of the bolt and projectile exit. The data showed that the effect of lubrication is not dependent on the cartridge type or temperature tested. The bolt forces increased with temperature; however, the increase was due to the associated increase in pressure caused by the elevated temperatures. These results provide direct data on the synergistic relationship between lubrication, cartridge pressure, and the force exerted on the bolt face.
That bold part is the truth. Nothing you or any other AR15.com forum reject is going to change that.
