    The bolt is most definitely not in battery. Monitor your bolt as you fire, because you should always entertain the idea that you may strike a cartridge out of battery which can lead to catastrophic failure of the trunnion. More importantly, firearms can be repaired and replaced. You cannot be, and we only get one of you.

    HK pattern roller delays will generally not allow the pin to travel far enough to extrude from the bolt head when out of battery, but better safe than sorry.

    Without seeing it in hand, it is hard to determine if the pack is low on the receiver, but it is far more likely we are dealing with further issues of ejector/extractor. If your extractor is not stiff and fixed on the bolt, we are dealing with failure to remove from battery, possible feed issues, etc.

    I'd hate to send you off buying more parts than you don't need, so let's find some other opinions as they come in this thread.

    Further, would you send a picture of your extractor spring and a few angles of the extractor? One of the ejector face wouldn't hurt either.

    Most importantly, get a read on your bolt gap and kindly report back.

    OP, if you are still having issues with your POF, contact Martin Millican (Service Manager) of FEDARMís. Martin helped me out and with the issue on my SMGPK pistol which was having slam fire issues (firing burst). FEDARMís end up sending me a replacement SMGPK. I picked up the replacement SMGPK pistol last week from my local FFL. All is GTG with the replacement SMGPK pistol.

    If you want to read the history of my issue, I post it here: https://www.hkpro.com/forum/hk-clone...ml#post3575358

    Yeah, I almost submitted the eForm 1 back in June for the SMGPK pistol. I have the eFrom 1 all done and ready for submission. During that time, I was thinking that FEDARM’s will just send me a replacement trigger pack in exchange for the defective one. But that was not the case.. FEDARM’s requested that I send the firearm to them for further inspection. I figured that I better hold off in submitting the eForm 1 until FEDARM’s complete their inspection.

    After getting an email back from FEDARM’s stating that they will be sending me a replacement SMGPK. I had a sigh of relieve that I didn’t hit the submit button for the eForm 1.

    Now that I have the replacement SMGPK pistol. All I have to do is just edit the serial number on eForm 1. BUT, before I submit the eForm 1, I want to break her in first and shoot another 500 rounds just to make sure that the replacement SMGPK pistol is good to go. Just a precaution.

    I’m sure that FEDARM’s will work with you on the issue that your having and possibly send you a replacement SMGPK if the issue is not fixable.

    As for the eForm 1, maybe BATF can cancel your submission and give you a refund (HOPEFULLY).

    You can cancel an approved form 1 within 30 days of approval and receive a refund provided a short barreled rifle was never manufactured.

    Update I sent the gun back and they changed the bolt out and got it running.

    My first range trip I took it out and started shooting it suppressed. On the 13 shot experienced same failure with spent brass in chamber. I then had the failure on the next mag.

    Took suppressor off and shot several mags without the issue until it happened again, but the extractor was already lose at this point.

    What’s interesting is when this failure happens it partially unseats the mag. Could the bolt be unlocking early?

    Could something be going on while shooting it suppressed to cause this? I’ll contact Pof again but wanted to hear if anyone had any suggestions.

    It also seems to have the least failures with my reloads that are Loaded light.

    I plan on trying the #28 locking piece to see if this will solve the issues running suppressed unless anyone has any other suggestions.

    New to the forum and this thread gets my first post! Have you tried the #28 locking piece yet? If so, did it fix the issue you’re having? I’m torn between the Atlantic’s Pro POF version of the RS and the PTR KT...I’m leaning towards the POF to form 1 it.

    I just took it out, it greatly helped my issues but it didn’t resolve it. Frustrating. My failure raise wheat to perhaps 2%.

    It’s my fault at end of day I am sure I would have gotten a replacement gun from The importer if I haven’t already formed 1 it.

    I was looking the gun over more, does it look like the ejector sits too low relative to bolt?Attachment 246548

    I am tempted to try the g3 extractor spring as one last Hail Mary prior to sending it to a builder?
