View Full Version : AR bolt cleaning?

July 23, 2012, 08:28 PM
I disassemble the BCG after everytime I shoot. But how often should the bolt itself be disassembled and cleaned?

Whats left to take apart the extractor, ejector, and gas rings? I have put thousands of rounds thru mine and never taken the bolt apart. The AR really doesn't require the maintenance people think, but if it helps you sleep at night go for it.

I usually take the extractor off and clean any trash out and inspect it for wear.

I have never taken the ejector out on any rifle. I only change the gas rings if it fails the gas ring test. Only one rifle ever had to have it done and it was a Bushamster that I believe may have had a rough bore that was eating rings. (Not mine, a friends)

You can go a long time just squirting more lube into it, but I would at least strip it down and wipe everything off every 500 rounds or so, just to inspect all the bits and pieces.

But it doesn't need to be spotless. Just get the gunk out.

Don't know, I just soak mine in Hoppes and blow off the excess. I'm not crawling through the sand or chasing boogey men so my requirements are different than some.
Direct from a 2 tour Iraq vet. They were never allowed to do more than pull the bolt and soak it in Hoppes#9(most of which I supplied-for that unit anyway). Some contacts burned 3-5+ mags per man full auto in under a minute but they never had a failure that could be blamed on failure of bolt components or built up dirt/crud in the bolt.

1. I never remove/replace gas rings unless they fail the test (stand carrier on end with cam pin remove, bolt should not completely collapse. If you want an extra margin of error, you can do the test bolt face down).

2. I clean under the extractor maybe once every 4k-5k rounds.

3. Unless I am having a problem with fail to eject, I don't mess with the ejector.

probably clean your bolt every 600+ rounds you don't HAVE to completely take it apart just use some spray gun cleaner and hose it down, scrape the crud out under the extractor or just soak it awhile in some cleaner.

add more oil and shoot more. I'll take it apart when I need to replace parts.
