Mike suggested just moving my sear to the pack that comes with the rifle. I figure that would require removing the blocking bar in the semi only pack. That's not a big deal but it would be nice to have an unmolested pack if I ever wanted to sell it. Especially if it's easy to mod my exsisting pack to work with the new ejector. Any insight would be appreciated.

Thanks

Yes ;-) Friend milled the front of the SEF pack to fit the ejector.

I recommend sending you exiting pack off and having Mike take care of it for you, in particular at one time the BATFE did not like us having extra sear ready packs, or so the story went.

I'm not a MM23 owner. My understanding is that the big issue with multiple packs is the trigger stop. There is a pin inside the right side of a HK trigger pack that stops the movement of the trigger. A pack for a semi auto does not allow the trigger to go as far back as the trigger in a full auto pack. If a full auto pack is in the auto position the "catch" (HK's term for the auto sear) will hold the hammer until the bolt group is forward into battery. If a full auto pack has the trip lever, catch, and the lower notch in the hammer removed, if the trigger goes far enough back, then there is noting to stop the hammer from following the bolt group back into battery. This could cause a slam fire. If a slam fire could be made to happen, that would meet the definition of machinegun. So if ha sear owner has more sear ready packs then he has registered sears, the Tech Branch would consider him in possession of an unregistered conversion device. Good luck with your MM23 trigger pack project.

JohnS,

Molestation of your pack consists of only having a deeper groove cut into the the notch where the ejector lever pivots down into. It's not a big deal. I guess it'd be equally as reasonable to either cut that notch in your existing pack OR move your sear and innards over to the already notched semi pack that comes with the gun. I have 2 sears and Mike helped me set up a pack in each of the manners described above. They both work fine in my MM23E

Hope that helps.

My pack did also need the shelf clearance cut increased, but I'm not sure it was really in the right place to begin with. We found a number of things 'wrong' with my pack when TSC went over it.

could someone please post a picture of a modified pack.
Someone posted a pic of it a long time ago. The next time I get my guns out I'll try to snap one for you.

Basically its a deep angular more box like cut in the top right aspect of the pack frame if viewing it's face. It matches and accepts the ejector lever which is seen here:

Make sure you check the 21E ejector for clearance on your hammer - if you use a non-E hammer the radius was not relieved for the 21E...
