    Default PTR 9KT - Failure to eject

    bought a new to me PTR 9KT - gun looks flawless. $1500 cash, including a holosun green dot and 4 mags plus all original case.

    Imagine my surprise when I take it to the range, and it fails to eject on about 5 of all 30 rounds in every mag. To be clear - it extracts no problem - it sporadically ejects - which is weird, because when it does eject - it does so with a fury - I bet it would shoot the casings 40' if I didn't have glass next to me. shooting 115gr.

    I'm sure the previous owner had absolutely no idea it did this....

    I don't know anything about MP5's - this is my first, did some digging around on the forum? possibly new ejector spring? maybe try 147gr ammo? (gun range 100% out of ammo due to COVID - only had personal 115gr stashed)

    submitted an email to PTR about 5 minutes ago - no idea on their responsiveness to customer service issues, but I guess I'm about to find out.

    Default PTR 9KT - Failure to eject

    Not aluminum cased ammo is it? Thatís the only thing that ever doesnít run in my all German mp5. Is the extractor nice and stiff? Whatís the bolt gap?

    115gr, 124gr, 147gr, all should run fine.

    Chamber clean? Whatís the tip of the ejector look like? Is the ejector lever at all sloppy side to side?

    Nope it was S&B brass case.

    I'm about to take it apart to clean it. I'll let you know.

    I had this same issue with a pof. Replaced the ejector ($36 hk gen 3 at brownells) and ejector spring from hkparts.net. I also replaced the extractor and extractor spring (parts are about $40 from hkparts.net). She runs like a champ now. So for about $70 you should have that thing running right and you still got a hell of a deal on it

    So... I have to drill out a rivet and put in a new ejector? I’m not sure how comfortable I am with that. Never messed with rivets before

    Any one know how PTRs customer service is? Will they take this thing back?

    Correct term is the Ejector LEVER. It's in the trigger pack on the left side. It's held in by a spring loaded axle. Pop out the axle lift the ejector lever out and replace it with a new one. Be careful not to lose the ejector lever SPRING or you could just replace it as well.
    The ejector lever is a sheet stamped arm that protrudes forward of the trigger pack and as the BCG recoil it ( the lever ) flips up and knocks the empty casing out of the ejection port.
    I'm not aware of a rivet that would hold it place unless the PTR's are different from all the rest.

    The ejector lever is held in by a 1/4Ē or so diameter stepped pin. Its the pivot point right in the middle. Itís only about 3/16Ē tall. It pushes out from the inside. The spring in the back usually doesnít fly out, itís really pretty easy to take apart. I swap them all the time to switch from 9mm to .223 to .308 as each uses a different ejector lever. It should pivot easily, and not have any side to side wiggle. Itís the bolt head that pushes it down, make sure the top edge of the rear end of the lever isnít worn.

    Sorry I should have specified ejector lever. It’s an easy swap in the trigger pack
