    Kevin and I are on it.
    Somehow the whole "contact the manufacturer first" got bypassed.

    PM...

    For clarity's sake; Kevin replied earlier in the thread, so he was obviously contacted, however, KAC did not have the opportunity to have their fixes applied. I am not saying that this is your fault, simply that the factory correction was bypassed. I'm not pointing fingers at you.

    "Factory fix" from KAC applied and gabuzz's SR-15 now has failure to eject malfunctions... Sorry but the commercial version of the gun is clearly over-gassed from KAC. I will be posting a separate new thread before the year runs out testing a 14.5" KAC against a 14.5" BCM. If the KAC gives me any issues at all its a goner quicker than you can say E3.

    I not sure if they are over gassed or not but I was surprised that my 16 inch KAC would cycle 223 ammo with a H2 buffer with a blue springco spring unsuppressed. I love my Knights rifle it runs great but doesn't seem near as sensitive as some people have said.

    In my 1st hand experience, the commercial version 16" SR-15 E3 legacy carbine (not the early versions with the smaller gas ports) is over-gassed when you run it with a suppressor attached because it was designed to cycle weak sauce .223 ammo; this compromise only effects those who wish to suppress their gun. KAC's commercial version 11.5" SR-15 E3 CQB SBR also showed (my first hand experience) to be over-gassed suppressed but was later remedied by installing an A5 RE and A5 H3 buffer.

    I may have to try a H3 buffer in my 16 inch when I get approved for my suppressor. Currently shooting it with the H2 and blue spring without the suppressor. I was just surprised that it would cycle that's all. I will be curious how 11.5 upper runs once I get it.

    Check the this thread, I still had issues using a heavier action spring and a BCM H3 buffer when the SDN-6 was attached to the rifle. Vltor's A5 system with the second heaviest buffer (A5H3) and a green Springco spring fixed my 11.5" gun completely. Unfortunately the A5 system did not fix the legacy SR-15 my buddy owns...

    Adding a heavier buffer and changing the spring aren't going to solve the issue of overgassing. It will simply cure part of the symptom.

    Putting the bolt in correctly might help...
