Well, y’all convinced me to send a check to Carlos at BPP for his 23E. Was told a 6 week wait so I’ll keep my fingers crossed.
Any of you shoot steel case ammo in yours? I don’t plan on ever dumping more than a 200 round belt at a time. Well... maybe a couple 200 round belts while letting the barrel cool lol. Curious what kind of round count y’all have through your barrels. $1000 barrels are eye popping considering it makes match grade precision rifle barrels look cheap. |

I have shot out 2 barrels, but I abuse them constantly with 300-600rd belt dumps. I bet one has over 20K the other maybe 10-15K. The 20k barrel throat got so bad the case necks would split on the steel. The other barrel is shot out but the throat is good enough to dump belts with. The rounds just go sideways now. I have 4 new barrels, so they should last awhile |

Ok, sear timing question.
When 'timing' a sear, what parts are getting 'timed'? How are they 'timed'? Are the same methods used for 23e's as MP5s? |

There is also the trip lever timing, which refers to where the carrier is when the trip lever is actuated, pushing the sear forward to release the hammer. The easiest way to measure this is with feeler gauges just like you measure the bolt gap. The trip lever has to actuate before the bolt stops, or else you can have dead trigger situations. Without welding and redrilling holes for your trip lever and/or sear in the pack, the easiest way to tune this is by modifying the tip of the trip lever (to make it release later) or making the notch on the hammer less shallow that the sear engages (to make it release earlier). You can also modify the carrier to change when it contacts the trip lever, either by welding and recutting it, or removing material. |

Thanks for all the help, everyone. Keep on dropping knowledge bombs; it's been a great help.
My quest has come to an end. As soon as I get it running, I'll do a write up and post some pictures. |

Why doesn't it run now?

At first, I thought it was lack of a re-timed hammer. Got a retimed hammer, and it cured all the non-belt fed hosts. They run great.
It runs fine in semi, with the semi pack it came with. With my sear pack, the rounds won't chamber... even bumping the forward assist. Again, fine with the semi pack. So, no idea... but all of the 9mm from my house has disappeared, and it's terrifying how fast ammo is consumed. |

Something must be in the bolt carrier group's way. Maybe the sear trip lever? Try taking it out and see if it'll chamber then.

Are you using the beefier HK21/23 ejector lever with your sear pack? Quote HistoryQuoted:
Are you using the beefier HK21/23 ejector lever with your sear pack? have you modified the the contour on the front of the trigger box to allow the front of the lever to fully seat when the bolt is going into battery? : If you are using a 21E feed block with a standard trip lever, you need to remove some of the material from the tip of the trip lever to clear the slide in the feed block. |

Not sure what a 21e feed block looks like, but I'm using the 21e ejector, so the last bit shouldn't apply. Quote HistoryQuoted:

Sorry for skipping your comment, KitBuilder. The trip lever contact was an afterthought as it caused feed problems. The tip of the sear trip lever would block the side movement of the slide on the feed block on my MM21E. The fix was to remove just enough of the tip of the trip lever to clear the movement on the feedblock. I had no problems with the 5.56 feedblock and sear trip interference. |

Yeah, it's an MM host. It was unfired-ish, got it on HK pro... or at least only test fired. There were some super light brass marks on the feed tray. Runs good with the semi pack.

Runs good with the semi pack. a lot of the MM guns wont run in F/A. Lots of timing problems due to the "custom" MM parts You need to find a friend who has a a running 21/23 and/or real german parts to swap until you find the problem. I would look at the trip levers and the bolt carrier. specifically if the boltcarrier has the grooves set up correctly for the trip. |

The ongoing saga of my mm23e problems has finally ended. Mike sent me a replacement receiver in mid-august. The new receiver has a perfectly straight front sight, and the build quality looks great. However, initial testing showed that it was still jamming, even with all of his recommended ammo. This time around I filmed every single shot, and after showing him the videos, he finally started acting nice to me. He promptly sent me a brand new feed mechanism, which resolved the jamming issues (I had asked to try a new feed mechanism over a year ago, and he ignored me). Interesting how that worked out.
Yes, Otte finally came through and took care of me, but I still believe it should have run fine from the beginning, and not taken 2 years and the threat of legal action to get results on a $12,000 gun. If anyone reading this is considering a michaels machine beltfed, you've been warned. This is the last time it was shot before I sold it, a couple weeks ago. https://youtu.be/eyfO14CfCIc |

I’ve been following your saga for quite some time and I feel your pain.
I also had MM23E but sold it and stop visiting HKpro for a obvious reason. For $12K gun, you shouldn’t have gone through that kind of joke. Glad to see you got something worked out at the end. Quote HistoryQuoted:
