The HK 50 series of weapons use a fluted chamber to aid in the extraction of
the the shell, because of the delayed roller blowback system (very dirty) blows
gas back in the flutes and helps to release the shell from the chamber.
I am wondering in your opinion, would a fluted chamber in the AR15 series of
weapons increase the extraction reliability of the weapon. It would obviously
get more dirty from some gas flowing into the flutes, but if it helps to release
the bond between the brass and chamber wall earlier, then it would in theory
increase the extraction reliability of the system.
Due to the less surface area holding onto the brass, this in theory would also
have less drag on the shell, tension on the case rim and extractor notch,
lessening the ware and tear in the extraction parts.
I also think the flutes would give large debris a place to go, keeping the contact surfaces free from blockage.
This is just something I was thinking about and thought I would pose the
question to people with more experience in these technical matters.
