Brass shaving ?

Brass shavings in the M14/M1A are not normal, even if most M1A's are producing them... Rather the shaving have an effect is unknown, except to the cases, or they find their way into the chamber.. Case shavings means interrupted feeding, among other things.. When a condition exists that is other than designed for,,, means somethng is wrong, accepting this condition is not a solution... Nobody wants to discover misalignment issues in their rifle, I do not believe anyone likes them. Some commercial M1A receivers are not always very good... "Always very good", is another example of the increasing use of compounding adjectives to explain away what is unacceptable, poor quality, shoddy, PC BS...

My current M1A shaved brass, cresent shaped pieces were everywhere, the ejected cases all had damage. The location of the damage to the cases was consistanct, slow hand controled feeding indicated the left side of the chamber entrance had a sharp edge, the entire entrance had a sharp edge. Removing that edge by lapping a smooth bevel solved this annoying issue.. Art

Totally unacceptable in a combat rifle.

Are "flakes" of brass, resembling powder, something that should be of concern?

Thanks from Dougboffl and Lurp

all shavings should be investigated to determine origin.

Can and are often cause by the extractor engaging the rim,, not the same as feed shaving.. You can smooth the edges of the extractor with a stone and do away with the brass powder.. Good question...Art

No problem. This is really a no brainer. Shavings mean reduced clearances. Reduced clearances in a combat rifle mean death!
