MP5KA4 (1:1) . Presenting my LEGO® MP5K! . Having been quite busy with college and work for the past few months, I have been doing a bit less building and have taken a lengthy break from my LEGO® MOC-posting sites. I am now back with some all-new models to show you!
Having toyed with the idea of building an MP5K for some time now and seen all the great MOCs that others have made, I decided within the last few months to try constructing one of my own. The Heckler and Koch MP5 family of submachine guns is one of the most well-made and widely distributed in the world, and I wanted the challenge of constructing an H&K firearm for the first time, which might then make it easier to build similar weapons in the future. Having chosen the MP5K as my project, I wanted to replicate one of its more modern and standard versions and settled on the ‘A4’ variant, which features four different fire-selector settings. I finished the replica during my Spring break from college.
This model bears the fruit of several significant breakthroughs I have made in my gun-building techniques. The first is my learning to build the width of a receiver in an odd number of studs. My MP5K is based off a 3-stud width, which can make it difficult to include normal features (e.g. working trigger, removable magazine), but provides the small submachine gun with a greater degree of dimensional accuracy when finished. The second significant stride I’ve made is in the trigger design; this is, to date, one of the smallest, working trigger mechanisms I’ve inserted in a model, and the MP5K is my first replica to use one of the curved animal tail/claw pieces as a trigger, instead of the less-realistic Technic angle connectors I normally have to use. I am also continually improving my ‘Studs Not On Top’ techniques for attaching detailed parts like the barrel and pistol grips while trying to strengthen the fragile connections that these components often have.
The life-size replica features a new, curved pull-back trigger, a four-position fire-selector switch, sliding cocking handle and bolt, line-up gunsights, and a removable magazine.
[Overall dimensions: 12.8” long, 1.8” wide, and 8.3” high (from top of gunsights to bottom of main grip). Total weight: 1.2 lbs. First completed on March 28, 2012; deconstructed on June 17, 2012.]
[The vertical foregrip incorporates thin Technic tires wrapped around its shaft.]
[The magazine removed; the magazine catch shown here does not actually lock the magazine in its place.]
[The cocking tab pulled back to open the bolt on the right side.]
[The bolt half-open, as visible on the right side of the weapon.]
[The weapon’s line-up, look-down gunsights.]
[As on most LEGO renditions of the MP5, the front aperture sight has been simulated by a rubber tire.]
[The four fire-settings available on the A4-variant of the MP5. This ambidextrous switch is physically linked to its twin on the other side of the gun.]
Thanks for looking; let me know what you think I should build next!
