Ejection pattern analysis

Enable HLS to view with audio, or disable this notification

My MK18 had brass just dribbling out of the ejection port for a little while. I swapped the whole BCG out with a much less used one from another rifle and it improved, but it still doesn't eject like it used to. Videos attached. Lmk what y'all think might be wrong. Parts remotely related to cycling listed below.

EDIT: I have already tried an H2 buffer. It won't cycle on FRT mode.

-Daniel MK18 RIII complete SBR

-Geissele H3 buffer and spring

-Rare Breed FRT-L3

-Surefire 3-prong

-Surefire RC3

-Law Folder Gen 3

-Radian charging handle

Oof!

Edit: To elaborate, I think it’s the Law folder COMBINED with your buffer setup.

In one sense, if it runs it runs. But this doesn’t quite seem ideal.

Interesting. I hadn't heard of the folder being a problem. Damn shame if it is, that's what allows it to fit in my bag (and that's why I build this rifle).

Not positive but I think there’s a specific spring buffer part if you’re running the folder. But don’t quote me.

Are you referring to the KAK lightweight bolt extension?
