My MP5K project (MP5.4K-Uber Kurz) 56k warning

Bulldog-IL · February 14th, 2008, 04:21

When I bought the Kurz along with my Aug I wanted it to be my secondary side arm \ CQB weapon.
To make a long story short, I wasn't satisfied, so i decided to upgrade it a bit.

First of all, I wanted a 330 fps weapon, not a 215 one, in order to do so I swapped into a longer barrel (30 cm instead of the 11cm) and also replaced the cylinder to fit the new barrel length.

I also replaced the bushings to guarder metal bushings, a CA 100 m\s spring and covered the new inner barrel with old, china made AK 47 outer barrel. I got my 330 fps but it looked strange.

The next thing was to install a CA M4 \ M15 retractable stock, which is a very easy upgrade that contributes to the aiming and the over all look.

I tried it a couple of times and decided that a change of battery is a must. So instead of the 8.4 V, 600 mAh battery I took an 9.6 v 1700 mAh one, which was a bit big to fit into the battery place inside the K, it needed to be split and rewired.
By that time I got that M203 crave again, so I ordered a RIS from UNC and bought myself a CA M203.

The outer stick as you can see was placed into plastic tubing, later on I changed it's position and made it removable with RIS adapter.

Finally, yesterday I got my RIS in the mail, here is the final look (for now) of my MP5.4K

It shots 15 rps at 330 fps.

What the hell did you do to that poor K ?

Hectic · February 14th, 2008, 09:14

Verry nice!
If I may suggest putting a light or laser in the end of that batt just to make it look like something

Its time to unpimp the MP5K!

SDS_ShooterMcGavin · February 14th, 2008, 09:21

Bet that gun will be tearin ass in CQC..

Crunchmeister · February 14th, 2008, 10:09

I like it. I think the barrel looks a bit odd. A silencer would look better, I think. But otherwise. I really like it. It looks badass.

You should add a 6x24x50 scope on that beast

BC_K · February 14th, 2008, 12:34

Holy crap!!!

I thought I made some funky looking K's before.......NICE WORK MAN!!!

If you chop your bolt a bit, you can fit a 9.6v 1400mah ministick in your MP5K and avoid having an external battery. That will draw a 100m/s spring, no problem.

lol...that thing is made of win. cool stuff.

Murdoch · February 14th, 2008, 13:24

Good job on the work put into it, but haven't you just killed the reason for carrying a K around with you? You may as well be hauling another full-sized aeg, or an aug shorty so you can share mags...

Maverick0 · February 14th, 2008, 13:28

I'm not sure of the barrel length... I put a longer one in my K but not quite that long. Mine still rocks for CQC though...

I basically did the same thing here but covered the barrel with a silencer and got some after market internals for durability / slight RoF upgrade. Top is off with a claw mount and an rds. I should take some pics and put 'em up

The thing isn't half bad outdoors either. It's made a few people eat their words about small guns outdoors on more than one occasion

Should use the grenade launcher to house a larger battery.

Maybe a flash hider would look good hiding the long barrel.
