Introduction: H&K MP5SD (+ Internal Pictures)

Hey guys. Well, I have been working on this gun for almost (if not over) a week now, and I am not entirely happy with it. But as I cannot put my finger on what is incorrect,  I think you might be able to help me with that.

As you can see, this is my H&K MP5SD, the first one on this site. This is probably my all time favorite gun. The very first gun I ever posted was a MP5SD (a VERY VERY bad one. See step #3). So I decided, as May 19, 2012 was the day I joined and the day I posted my old MP5SD, I would post a better version on my one year anniversary. I am a day late, but what does that matter. =D

This gun is comfortable, hefty, and the permanent silencer looks great on it. The stock adjusts from being "closed" at 26 1/2 inches (total length of gun when stock is not out), to 30 1/2 inches open (total length of gun with stock out). Four inches may not seem like much, but it is better than you think.

As I said before, the gun is very comfortable, but I would say it is rather flimsy. The stock's bars are only a grey rod wide, so it is not very sturdy, but it is really the best possible under the circumstances. The mag can shoot tan connecters, or green rods, and I would expect it to get 50 ft., but that is just speculation.

The sights are alright, and are as close as possible, and don't look to bad. Now, you may be seeing a TON of broken pieces, but you really only need the four shown in the last 6 or 7 pics. Don't freak out,  not all of them are needed.

Some features of the gun would be:
New mech (see the last 7 pics)
Adjustable stock
Good range
Great sights
Accurate looks
Open to bottom attachments and sights (see pic 25 -26)

Overall this gun is more for looks than it is for shooting ability, but it can do both. Go ahead and take some time to look at the next 3 steps, as they will show you how I got to where this gun is now. (Note: No FP shown in pics)

Step 1: MP5SD V.3

I only changed a few things in this to get to the best version (V.4). Among those changes being:
I took out the fake charging handle
I exchanged the mag fore something less-wide

Step 2: MP5SD V.2

This was my very first version. As you can see, I have a G36 stock on, instead of the classic MP5 adjustable stock, as I had not developed that yet. Many of the other changes are apparent.

Step 3: MP5SD V.1

This was my very first version, and among one of my very first guns. It is pretty bad...

could you just put a regular barrel on it?

author

Then it would just be a MP5A2.

author

this is modeled after the MP5 with a built in suppressor correct?

author

Yes, it a permanently silenced MP5...also known as a MP5SD.

Nice =D If only it could shoot better ammo like grey connectors. Looks nice and simple so it should be reliable. For the front sight try using a blue bendy rod.

author

That is very true. I did try using a blue bendy rod, but it looked worse than the one that is on it above.

author

Ok,apparently I replied to this but didn't =P Anyways, for mp5 style sights Im actually considering making my own knex pieces so they actually look correct since knex cant replicate some things. Too bad the bendy blue didn't work, I guess anything is worth a try for sights.

author

Ah, sounds interesting. Let me know when you "accomplish" it.

author

I will either be using wood or this really strong block of plastic from a cutting board. I will post pics if I finish.

author

Ah, I see. Sounds great. =D

Looks fantastic! How does the stock stay back though?
Also, I like how you included your first version of last year. This shows how much you've improved in building in just a year time

author

I am glad you like it. How does the stock stay back? Well, all you have to do is take a yellow rod, attach one tan connecter to it, push the yellow rod through the hole you want to determine the depth that you wan, attach another tan connecter to the yellow rod, and then push the tan connecters into the mini holes in the white connecter that you chose to make a "stock stop."

author

No problem, and okay

author

LOL, that might have been one of the longest explanations I have ever given...

Looks good! As for what may be just a tiny bit "off" about it, I think the trigger guard comes down too far. Maybe try bringing it up a bit closer to the gun.

author

Thank you. I would agree that the trigger guard needs to go up, but that is relatively hard to do, under the circumstances.

author

Yeah trigger guards are a pain and as always when you build something one way it's hard to make little changes without taking a lot more stuff apart.

author

That is very true. I don't understand why so many different guns have so many different (and sometimes weird) trigger guards.
