FTE after the gun starts to get dirty.  Which Extractor Upgrade kit do you guys recommend?

Why are you running an "extra power" action spring and an SMG buffer in a carbine? The SMG buffer does not have the correct reciprocating mass. I would try a proper carbine action spring and an H3 buffer. I would also install a "black" M16 extractor spring and insert.

Fail to eject, How?????

Is the rifle short stroking (will not lock the bolt back on the catch), the case being dropped before the end of stroke. leading to double feeds (one live/one spent) or what once it begins to foul???

Major description of the problem needed before we can even attempt to solve such.
