Somewhere along the line it became popular to say “I haven’t cleaned my AR in XXXX amount of rounds.” Apparently, the higher the number, the cooler you are.
This happened, I believe, because more people now understand the importance of running an AR wet than ever before. Even in military circles, where the mantra of “a very light coat of CLP” used to reign supreme, I am seeing old dogs learning new tricks and heavily lubricating their AR’s.
Certainly, heavy lubrication will keep an AR running fine, even after a lot of rounds.
However, I still choose to wipe down the internals with Break Free CLP on a rag after every shooting session. It takes less than 5 minutes, and it serves a dual purpose. First, it allows me to put eyes on common failure points and to identify anything that needs attention. Second, it allows me to get any foreign objects / debris such as sand, dirt, dust etc. out.
If carbon buildup was the only thing getting into my upper receiver after thousands of rounds, I might get on the “don’t clean just lube” bus. But that’s not how I shoot. I don’t sit at an indoor range and shoot from a bench. Even if there is only a small amount of sand or grit on my BCG, I’m going to get it out when I’m done shooting. There is no harm in that.
I’m not advocating scraping anything or doing a white glove cleaning after every time you shoot. I’m simply saying that a quick wipe down with a rag and CLP can do nothing but help.
I’ll take the ability to visually inspect my components and to remove even small amounts of foreign objects / debris any day over the cool factor of saying “I haven’t wiped down my AR in 8,000 rounds.”
PS. As for cleaning the bore…I do that when I notice a degradation in accuracy. I make it a point to confirm zero (100M with the carbines) before I do any type of training, and when doing so, also make it a point to try to print the smallest groups possible. That allows me to get even a small amount of training value on precision shooting every time I shoot, and also serves as an indicator of when I need to rod the bore.
