Teufelshund Tactical Heckler and Koch MP5 Rear Diopter Drum Install

[@aarontodd746]

Thank you for this video. I had it on my tv while installing my new rear sight.

[@Doc7788]

Thank you for this video it saved me so much time with the install of the drum. It took me a few tries but I was able to successfully get it installed.

[@MarkWilliams-w8g]

Thanks a lot. Couldn't have figured out how to disassemble the rear sight on my G3 clone without this video...

[@JayyBird93]

After watching 3 videos yours was the only one that had enough info to actually complete the job. Thank you!

[@vtxdaryl]

Man great tutorial, I watched several other videos and none were as complete as yours. I even got a small punch that made it easy. One thing I did do to mine was spray WD40 on the threads because I couldn’t move the sight. Once I sprayed WD40 on the sight it immediately started turning. Then at the end I kept my finger on the bearing that I would have lost and then reapplied my drum sight. Thanks, Daryl

great video a lifesaver and the only video online to get into the fine details thank you was a big help in my install.

[@crouchinghamster6407]

It took me about 6 tries, but I finally did it! I couldn't have without this video--thank you!

[@joeswiss6288]

helps a lot, thank you

[@subverto994]

Fantastic video! Made installing the diopter drum on my SP5K-PDW a breeze. Any chance you could do a front sight install video as well? I plan to run iron sights and want to replace my front sight with a tritium post, but there really aren't any videos explaining how to do it.

[@teufelshundtactical]

Thanks. It’s even more simple. Drive the roll pin that secures the front sight out from the front, push out the sight insert. Push in the new sight insert. Drive the roll pin back in from the rear.

Well done. Great photography for such detailed work.

Well...learned something new today, I appreciate it.

best one of these videos I have seen, breaks it down easy!

I have a clone, a MAC5. Love it, has been super reliable. Now around 300 rounds with no problems. However it shoots about 1.5" low. I have tried the HKParts tool w/ the screwdriver and also with snap ring pliers. I'm more successful using the snap ring pliers and I can see the detents fully pressed inwards. However, for the life of me the turret will NOT turn freely like I see in your vid and other similar ones on YT. Do you have any guesses why I'm having this issue?

[@teufelshundtactical]

Without seeing what you are seeing, when the turret will not rotate, it is because one or both of those detents is not being disengaged to allow free movement.

[@merc4hire308]

Very good video! Helped me a lot. Thank you.

[@Supreme19]

Very neat, and very simple, thanks James!

[@Y34RZERO]

I wish I saw this video first. I found a different video that didn't use the tool like this but a bit from another tool to slide off the castle and slide on the drum without releasing the captive detents. I didn't know they were spring loaded and would fly across the room. I thought maybe they were captive by another way but was wrong. I found the small detent but completely lost the spring. Any idea where I can find a spring?

[@teufelshundtactical]

You can always order your parts direct from H&K. Give their customer service line a call.

[@CannonCountry]

Perfect video thank you so much

[@Charles-lx4ph]

I definitely screwed mine down too far , fml, thanks for the videos they are very helpful!

[@F4iGuy599]

Great video and information from the best!

[@chuck1388]

I added an AimPoint T2 sight on Scalarworks 1.5 mount on SP5K. Question - were you able to sufficiently adjust rear sight so you could use it? I have raised the rear castle but as high as it can go without falling off. Despite this, it still is not high enough we’re I can use it with front sight to aim. T2 zero is perfect. I just would like to use iron sights also. You have been a great help to me on other questions that got me comfortable enough so I purchased the SP5K. I absolutely enjoy using it. It is my favorite firearm.

[@teufelshundtactical]

Come join us for training and we'll get you sorted.

[@chuck1388]

@@teufelshundtactical Great idea. Thank you for always taking time to reply. Best regards always.

Hello Teufelshund, there is a little misunderstanding how the sight finds its four positions. It does it not with these two bushings. There is a spring and a ball underneath the sight with are putting pressure on the receiver. Thats how it is indexing. Remove the setscrew, lift up the sight and you see the spring sticking out.

[@teufelshundtactical]

You are correct in that there is a small ball bearing and spring, but you are incorrect in your understanding of how the drum rotates and locks into each of the four positions. It is through the spring loaded plungers I described.

[@sammythedwarf]

Thanx James!

[@F4iGuy599]

Silly braces........YES! Used this for replacing the sight on my SP5K

[@samhummel156]

Keep em coming!

[@SpencerAK74M]

Iwas very proud of myself swapping this out on my bedside table... I blame covid boredom!

[@ironhorse8573]

My rear sight where you put tool into the dentent the spring has popped out and the detent is stuck under the spring. Is there another way to take that drum apart another way?

[@teufelshundtactical]

I'd have to see what you are talking about. You can send an email with photos or a video via the website.

This is kind of an unusual question, and I kind of doubt someone has ever asked you this before, but *is there any reason one could not use the castle drum sight on the G3 or HK33 rifle instead of the normal ranged diopter ones that come on those rifles?* I'm simply wondering if one of the castle sights allowed enough adjustment to be zeroed out to 200 or 300m maximum. I would think it would, but I notice the castle sight seems to be slightly shorter than the G3/HK33 diopter sights height-wise. Again, I know this is weird. I understand you would lose the ability to quickly adjust for 200, 300 or 400m by replacing the diopter with the castle sight...but sometimes I have a hard time seeing 300m targets using the diopter sights if the target itself is a really dull color, or if the visibility that day on the range in general is just not very good. I've used the "V" notch of the G3 diopter out to about 200 and it is ok, but I like the more pronounced U notches on the SP5K/MP5K PDW castle sight, especially the one that is very narrow and deep. They just seem to be more simple for my eyes to see and use sometimes than the G3 diopter sights. Just wondering if this was possible. Thanks.

[@teufelshundtactical]

It will fit, but there would be no conceivable reason why you would want to mount one. The G3 already has a v-notch setting for close targets.

[@dexm2010]

@@teufelshundtactical Understood. Thank you for this info!

[@Skylyned]

Two hours later and the first detente still pops away from capture when rotating to access the second detente. Starting to think something is out of spec

[@teufelshundtactical]

It can be tricky. If you can’t sort it yourself, you can send it to me and I’ll get it done.

[@Skylyned]

@@teufelshundtactical I finally got it working. I found that if I rotate it so it is halfway in-between detentes, where I have access to both detentes without having to rotate it under flat even pressure, it is much easier. With both detentes exposed, and downward pressure with the tool, you just press each detente with a punch until you hear it click. Holding downward pressure, then rotate the drum down.

[@FancyGothicKnight88]

My drum sight is kinda hard to rotate. Did I screw is down too far?

[@teufelshundtactical]

Without seeing it, I don't know. I would suspect you either do not have the threading lined up or have not properly captured one or both of the detents prior to rotating the drum all the way on.

[@shorty7943]

Well all i have to find now are 2 Original Heckler und Koch MP5 Rear Diopter Drums... which is not easy.
