Hey everybody. I'm not sure if you guys will remember me or not. I did a post in July that caused alot of drama. It was about surviving in the wilderness for 20 years. I realize now that that is probably not practical. I will still prepare for the worst, but I'm sure I won't last 20 years in the wilderness. Anyway.... here is what I'm wondering now........ If I go out into the wilderness with my AR15 and 200 rounds, and my cleaning supplies.... at what intervals should I clean my gun? Would it be better to immediately clean it after shooting it each time? Or should I clean it on a regularly scheduled interval? do you see my dilemma? I want my cleaning supplies to last the optimal amount of time and at the same time make my gun last the optimal amount of time. what would you guys recommend? do the solvents go bad after a while? that could be a factor right? i would hate to ration it meanwhile neglecting my gun, only to find out that the solvent has lost it's potency. does it matter how many rounds I've shot through it? I would hate to waste an entire clean on just 1 round. right now Im leaning towards this solution: after shooting the gun, wait 2 weeks or until any hostile threat is gone and then give it a routine clean and lube. If I've gone 2 years without shooting it, maybe give it a routine clean and lube. If when I shoot the gun, it's less than 10 rounds, I will give it a very conservative cleaning. If I shot more than 10 rounds through it, I will give it a generous cleaning. Here is another tough question: what ratio of cleaning supplies should I take? remember I don't want any excess weight in my pack. So when my solvent runs out, it would be ideal if my lube/patches/brushes were all spent as well. Hopefully that makes sense. Also are there certain parts of an AR 15 that I should worry about cleaning the most? should i not clean the receiver as much as I do the barrel? it seems like the barrel is the main thing I need to keep clean. I plan on getting a "gas pison" model rather than the "direct impingment" model, since it supposedly runs cleaner.... i.e... doesn't poop in it's own action (as somebody stated last July). It just poops on it's own piston now.
