Feel free to run/build your guns/bolts however you see fit. No worry to me. Just keep in mind the old axiom, "There's more than one way to skin a cat". Your way works for you, however that doesn't mean it's the only way.
You and I both know each firearm is a completely different animal unto itself, and what works in one, has a distinct possible of NOT working in "the same" gun for someone else.
It wasnt military-wide, it was M4A1s with KAC QD can attached. Cyclic rate exceeded the optimum rate for reliable extraction.
AR15s, M16s, and M4s had run without an O Ring for decades prior to that.
People with no understanding of SOCOMs unique challenges with going suppressed and unsuppressed said, SOCOM made their M4s better with O rings around the extractors. They know whats best, so we should put those in too.
By installing an O ring around the extractor spring and increasing tension that high, it increases the wear on the extractor itself during chambering because the extractor has to snap over the cartridge rim with more tension on it now.
Its a bad band-aid that works temporarily on an improperly-configured carbine, as long as the extractor is built like a tank.
For going from unsuppressed to suppressed and vice-versa, its better to be able to adjust the gas settings, or use a flow-through/low back pressure design.
My personal approach is to just use a Bootleg Adjustable gas carrier.
I have had zero Failure To Extract malfunctions with that set-up, and I put the gas setting on fully suppressed.
Cyclic rate is tame but more than sufficient for reliable operation.
