I took my M4 out to the range this week, on Thursday. Put about 230 rounds through it, Russian ammo.
Do I need to do a full-bore cleaning (pun intended) and by that I mean: Clean bore and chamber with foaming cleaner. Followed by brush with Hoppes. Followed by patches through bore with Hoppes. Followed by patches until they come clean. BCG soaked in Carbon Killer, full disassemble, scrub, reassembly, completely lubed. Full chamber cleaning and scrubing, full upper and lower cleaning with NC Brake cleaner. Or.... Can I just hit the changer with NC BC and chamber brush. Foam the bore and run snake. Blast BCG with brake clean and lube it down without disassemble? How often do you guys give your AR a full cleaning? |

I clean mine every 500+ rounds or if it is very windy dirty outside. Like the other poster, a few patches down the barrel + bore brush. I do take my BCG group apart every time though. Oil and back together. |

Disassembly, cleaning, reassembly and lubrication the bolt carrier group is normal cleaning which should be done every time. Same as using CLP in the bore.
I do not use copper removing solvents or a bore brush as I see no benifit to it in a chrome lined brl. I've got one brl with 7,575 documented rounds through it. Its never been cleaned with anything but patches and various versions of CLP. There has been no noticable decrease in accuracy over the life of the brl. When the accuracy fine does start to worsen its more likely to be from throat erosion than copper fouling. |

You take the BCG apart, oil it, but not clean it every time? Of course I clean it but that consist of spaying it down with Rem oil and wiping it off. Any carbon build up gets a few hits with a brush or scrapped off with a knife if that bad. Other wise, it's Rem oil and badda bing... |
| I clean after every shooting session. I don't use a bore brush either though. I take apart the upper, including the BCG, and clean everything with CLP, run a bore snake down the barrel a couple of times, and lube with EWL during assembly. I don't clean in as in preparation for an IG inspection like in the .mil (break out the dental picks and get the weapon clean like new). |

Never used anything other than CLP, either, although I may try something else when I use up this bottle. M&P-15 with 1,960 documented rounds. I completely field-strip, clean, and re-lube my rifle each time because it's my patrol rifle; I don't want to stake my life on a dirty rifle if I can help it. |

Ol' Painless has a good page in his arfcom famous Box O' Truth page.
Box O Truth I clean the bore, chamber, BCG & bolt after every shoot. Since you're not using corrosive ammo with 5.56, you really don't have to go nuts cleaning every time. Apply some CLP, especially if rust is a problem in your area, and you should GTG. I also like to run a wet patch with CLP through the bore when I'm done. It's not the strongest cleaner but it will work loose some of the fouling as it sits, just remember to wipe the bore dry before shooting! I use Hoppe's too, good stuff. I've tried others, but have gone back to good ole' Hoppe's #9. Love the smell of it.

I dissemble the BCG scrub everything with the plastic "toothbrush". Chamber brush, bore brush, hose it with NC brake cleaner. Mop w/ CLP. Hose down BCG w/ CLP wipe with rag, reassemble. Wipe everything down with the rag that had some CLP on it and back in the safe it goes. Every time I shoot it, but then again I go through at least 200-400 rds each time. I have a few AR's in different platforms so they don't all go out with me each time. When I get some carbon buildup in inside the BCG and the back of the bolt, if it is too bad I'll scrape it off. I'll also toss around a q-tip or two in the lower if it's too bad. Same routine I had in the Corps but with brake cleaner instead of a million patches.
Edit: It also depends if it is corrosive or non-corrosive primers. If it is corrosive I "get after it". |
| I clean the bore and chamber and bolt carrier assembly really well since those are things that really matter the most. But I still do a good once over on the insides and outsides of the gun with paper towels and CLP. I do this after every range trip. Gotta keep the rifle running smooth. |

I clean my main weapon every time I shoot, but it's a patrol rifle so I like the security of knowing that its always clean. I have run it dirty a few times and still have yet to have any malfunctions, but peace of mind on the street is worth spending a half hour or so cleaning it every time I shoot.
My fun range rifle gets a lot less love and still runs well. Full cleaning about every 2k and other than that just keep spraying and wiping off the CLP. |
