I went shooting with a good buddy of mine who just bought a new AR from a local sporting goods store. I showed how to remove the lower and upper as well as the bcg and charging handle, told him to take it home and use a little solvent to remove the factory oil and clean it and re-oil it himself before we went shooting. He did exactly this but he bathed the thing in oil. There was oil dripping from the bcg and coming out of every opening on the lower (pretty sure he drenched every part in oil except for the frame of the gun itself!). Besides being an unbelievable pain to clean are there any risks to the gun except for crucial parts getting clogged with dirt and gunk? What are some of the best ways to get down into the hard to reach areas of the lower to remove the excess? My ways are clearly not working on this unholy mess.
