Hey guys recently took a brand new AR to the range for the first time. Before I went I cleaned everything up and heated it up to apply some frog lube. Went to the range on Monday and shot about 75 rounds through it re-applying frog lube during shooting. When I got home I noticed metal shavings on my bolt face and at the barrel neck. Is that normal for a new rifle or is something getting caught up or is the frog lube not working properly?

If you run out you can have some of mine. I have tons of shavings in my riffles. But all of my riffles shoot fine

What type of ammo were you shooting, what did the shavings look like, and could you see any place the shavings may have come from (wear on chamber, charging handle, etc)?

i dont own an ar but see if the shavings are magnetic, if they are, not good. if its lead or brass or copper they are not magnetic. i only spray gun oil in my aks so they dont rust but nothing else adn i never get any shavings.

If you cycle the bolt does it bind anywhere? Abnormal grinding sound? As said, aluminum or steel shavings? Take the bolt out, disassemble and look for damage to carrier, bolt, pins. While its out check the upper receiver where the carrier slides( I'm guessing that's what it is). Also check the lugs and where they lock into the barrel. Its its only marginal shavings it just could have been initial alum wear and there is no damage. Similar to what happens in a new engine breaking in, you'll find shavings in the oil.
If theres no serious damage seen during your inspection, Take it apart clean well and lube well and shoot some more. You should be ok.

Did you check the spent shells to see if the shavings are coming from them?

A small amount of brass particulate on a bolt face is not unusual nor indicative of a problem. Steel particulate is a concern.If you are not using a Ni-Boron BCG keep the BCG well oiled....AR's love to be wet and oily. Hmmmm is that obscene???

don't over do it with the frog lube, you should not be applying it at the range, read the application instructions and follow it thoroughly otherwise you will be one of those guys that say "frog lube is no good it gums up my gun"

Only because it was the first trip I re-applied. Did a quick wipe down to make sure nothing was abnormal then tossed a little on at the range.
I figured it was brass but it was more than I usually see that's what concerned me. Thanks for the replies!

Exactly! You should see the bore and bolt face on my M14 after shooting 100 plus rounds. Looks like a brass snowstorm in there.

M14's are notoriously hard on ammo, Dings,scrapes and dents all over the spent cartridge.
