Knex UMP-45

Knex UMP-45
Alright I met your wishes for posting the UMP tonight. Bare with me here my camera was having a hard time focusing and I was still under the twitchy effects of an energy drink... Anyways the instructable is for mostly experience builders.

It features a removable magazine, fake charging handle, top and bottom rail with a foregrip attachment, and overall awesome looks. This version uses a full stock but feel free to make a flimsy open one.

Also behold the product of German and Russian engineering- The UMP-45u. Lol I swear though doesn't it look like an AK-74u combined with a UMP? It's not included in the instructable but it shouldn't be hard to figure out how to mod the original to this. Anyways on to the instructable.

I would rate this gun as...
A war gun (main)- 3.5/5 It's pretty good but it isn't super powerful for its size. It does have a high cap (for dark greys) removable magazine which is very useful and it was perfectly reliable for me while I had it built.
A war gun (secondary)- 4.5/5 It would serve as an excellent back up for power weapons. I would use the compact version with the same magazine though. The regular version is larger than it needs to be for a battle.
Something fun to play with- 5/5 By far one of my funnest weapons. It looks awesome. It works amazingly. What's not to love?

Alright sorry I couldn't be bothered to take this whole thing apart. It would have taken me forever to take pictures and upload the instructable (I still have homework to do and dinner to eat). Take you time and look at it carefully.

1-3. Different views main barrel and receiver area. Sorry I couldn't split it up more.
4-5. Make this piece and add it in here.
6-7. The muzzle. Sorry I was too lazy to take this apart too. It shouldn't be too hard to figure out from both of these angles.
8-9. Fake real barrel? The bullet travels through here but it isn't the real barrel on the real gun so...
10. Attach the muzzle and whatever you want to call it.
11-12. This is the bottom rail and how you add it.
13-15. Make this part (yellows don't need to be cut I just had them on hand and make the gun look better) and connect in these places
16. Then connect both parts to get this.

Alright the hardest part is done.

Im sorry to say that ,functionaly, it isnt great. However it is probably one of the best looking models i have ever seen and I keep it on a shelf in my room because it looks to good to dissasemble. 4* :D

It might just be me who gets this but when I fire, the grey clip get stuck in the barrel so it doesn't fire. but it is ok at firing rods bigger than blue.

ps, sorry for late reply, comp broke

May 8, 2011. 5:33 AMKaloki45 says:
What do you mean when you say that you can use a ball joint instead of tape? I just can't seem to figure out how to attach that white rod with the blue clip.
May 3, 2011. 12:47 PMsandmman says:

Apr 2, 2011. 10:02 AMCuddlesMcT says:

Apr 5, 2011. 11:13 PMbhuty says:

Apr 9, 2011. 1:32 PMCuddlesMcT says:

Nice! I'd make it if I had any yellows left! I had to spare the butt bacause of the lack of them D:
Oct 18, 2010. 8:39 AMTheFoofinator says:
That, my friend, is awesome, unique as well, I've never seen an internal grey clip mag pusher!
Oct 21, 2010. 9:04 PMCuddlesMcT says:
Thank you :)
Oct 14, 2010. 8:51 PMDJ Radio says:
Not bad, but it reduces the capacity of the mag.
Oct 15, 2010. 11:25 PMCuddlesMcT says:
true but i just dont like the huge rod sticking out of the mag
Oct 16, 2010. 8:48 PMCuddlesMcT says:
:D lol Wow. 3 knex pros commenting me :). *faints
Jun 30, 2011. 2:15 PMDJ Radio says:
We aren't exactly pros, we don't get paid for any of this. Technically the only pros are the ones the Knex company recognizes and Crestind to an extent because he runs KI and makes money to keep the site going.

k'nex pros basically are gods in the world of k'nex

Does the grey connector have to be broken on the muzzle part?
Mar 20, 2011. 9:30 AMbhuty says:
how comes the piece count doesn't include the green connector (the four slot one)
Mar 22, 2011. 2:18 PMchopstx says:
This gun uses 10 green connectors.
