Bolt Carrier... How Clean is Clean?
Ok, so the inside of the bolt carrier where the bolt rings are gets the most dirty of any part of my rifle. The fouling get really heavy and built up in there. To add to it, access is limited to Q-Tips. I can never really get it clean and it takes forever. Any tips or suggestions on this area? How clean does it need to be and how do you clean it easily?

Everyone has their idea of clean.

Clean enough usually means that the rings remain loose, and the bolt moves easily.

Those that are fastidious may want to have a spare bolt BCG for show.

-Spray your cleaner straight into that opening in the BCG (w/ bolt removed of course)
-let sit 2 minutes or so
- Taking A shop paper towel that has cleaner spayed on it you can use your smallest finger to force move it aorund in there picking up dirt. You wont be able to get it in all the way but thats ok.
Can also force the end of the shop towel with the end of a toothbrush and then just pack the inside with the shop towel until full, OR you cna also ue a toothbrush indie before stuffing paper in
(-If badly fouled you can use a handgun barrel brush (like for 9mm or 357 Mag ) on the inside of that opening prior to using the shoptowel/finger method)
- Do 1-2 times (or multiple times if putting away for long term storage)
- Give it a light coat of oil inside ( or heavy if putting away for long term storage) A q tip can come in handy for this.

I will disagree with the suggestion of oiling the insie of the bolt carrier. Any oil will immediately turn to sludge on the firing of the first round. Subsequent shots will bake the oil into a nearly impossible to remove crust. The gas rings should be DRY. The interior of the carrier should be DRY. Oil the front half of the bolt and the cam pin.

The firing pin should be dry also.

As far as cleaning goes, I like gun scrubber or (in a pinch) carburetor cleaner. It dissolves the nasties pretty well.

ATF brushes on, let is sit for a while, wipe off the soot.

Apply a thin coat when you are done. It cleans while

you sleep. Later wipe it off, & final coat lightly with Mobil1.

Brown Vinegar for the baked on stuff.

Shock it with Janitor's Ammonia.

The cost of all these combined,

(a quart of each) is about what you spend on

3 ounces of Mystery Miracle Sh!t, and it will

last you for many moons.

I dunno Robo.. One of the lublished schematics show to heavily oil the hole for the cam pin which will also result in a significant of lube getting into the bolt/BCG interface.

I would only recommend heavy prelube there prior to storage anyway.
But will not fire it dry in that area :)

I am a little wary of putting wire inside there. It looks like its only lightly chromed and easily scratched.

I dont run my gas rings dry either but I dont use a oil that gets hot and gums up either. I use Mobile 1 synthetic 5-30 I like it thin so it doesnt get gummy and it does not burn off either . I had one set of gas ring go right at 8000 rds and they were still working but very very loose. To each their own ,but if it moves and its metal to metal it needs light lubrication. Hell even the AK I recently bought was bone dry , I cleaned it up and do the same thing with it and its much smoother than day one when I bought it . The mobile one cleans up easily , I never have to scrub the inside of the carrier , I spray them with carb or brake cleaner and if its real tough I get the foaming bore cleaner out that I use on my BP gun . I think picking the right kind of lubrication is key to cleanup . I have tried probably 12 different kinds of lube and always go back to the Mobil One . Frog lube is good but it has to sit on the parts and needs relubed after a while , few drops of Mobile and Im up and going immediately . The Lucas gun oil was ok but it got gummy after sitting a long time . Rem Oil disappears and dry up after a while its not a good lubricant . Hoppes gun oil works but not long lasting , burns off quickly , Fire Clean works pretty good , havent had time to mess with it much since the ammo shortage came into play. I use what I know works best for me .

The how 'clean' question has turned to 'lube' and moved towards 'protect'.

Appropriate time to mention BreakFree CLP; it has served me well for years.

I want to start a thread titled "How clean should my chicken coop be"
