How do you re-assemble a MP5 Bolt???

The Mother F__ing bolt is really pissing me off.......

I just got back from the range with my Omega MP5 pistol. Shot great, field stripped it cleaned it, now the Mother F___ing bolt will not go back together......

Sorry for the rant, I have never had so much trouble putting a bolt back together.......

Thanks, I got it back together by putting in the locking piece/firing pin first, then sliding the bolt over it, and FINALLY having it lock back in place.......

Oh how I remember the first time disassembling the bolt and not being able to get it back together again.

I feel your pain.

Written instructions were useless.

Thankfully.... I came across a similar video.

HK91 bolt is much harder if you don't know the tricks.

Let our very own Joe does the trick.😁

The bolt came apart very easily. At that point, I felt it would go back together just as easily.........or so I thought........Grrrrrrrrr........

Now that I "figured it out", I have been taking it apart/re-assembling it, many times now.

Very true. Putting any roller locker back together can be very frustrating if you don't know the tricks. It's all part of the initiation.

I have a small block of wood on my bench. I push the carrier catch spring lever down on an edge of it while turning bolt head. Makes it easy to turn as the catch spring pressure is released.

The 9mm bolt head, the topic of the thread, does not have the lever. Good idea for the rifle calibers though.
I don't use anything aside from fingers to reassemble my rifle caliber bolt groups. As said above, knowing the tricks makes all the difference in the world.
I don't live on the boards but I have to admit, having seen what seems like hundreds of threads asking about how to get a 91/93 bolt group back together or what to do about popped out rollers, this is the first time ever that I've seen someone asking about how to reassemble the pistol caliber bolt group.

I started out with a PTR, so when I first took my MP5 clone apart I was sure something with the bolt was broken it was so easy.

** Old thread and used search feature and voila, looks like I wasn’t the only frustrated poor SOB, errr maybe I was cause it’s about 5yrs old although.

So after firing 200 rounds, figured it was finally time to strip her down for a cleaning and oh my......what a complete PITA this was!!! Was able to figure out concept without firing pin/spring in but could not get it figured out for true assembly once the firing pin/spring were in........the Bolt would not rotate enough, nor roller not push in as in the other above video.......but somehow, finally by a stroke of luck and numerous curse words I got lucky and found that sweet spot and was able to rotate bolt enough to clear and align properly (using below video method). I should have practiced it a few more times but was glad it finally worked so quit while I was ahead......today the bear almost won.......

Thus my initiation is complete, can’t wait to experience the same discord with my PDW.

Anyhoo, this Video and the above videos kind of helped, but definitely takes some repetitions (and a few curse words) to make it work......LoL

I laughed when I read the original post, since I had the same frustration with my HK91 30 years ago. Took me 45 agonizing minutes before I figured it out. That was pre Youtube days, so I had to keep going trial and error.

I'm glad you got it figured out without going Postal
