This is my favorite creation thus far. The HK416 in LEGO has a lot of engineering inginuity incorporated into the design. This includes the usual features to advanced, "how does he do it" marvels with bricks.
1. Full scale; 1:1; Life-sized
All of the above. I researched the dimensions of the HK416's overall and barrel lengths and used those to size up images of the 10" and 14.5" variants from hkpro.com. These images I printed out and used as a backdrop comparison of size between the real HK416 and my own.
2. Full size, curved, and removable magazine
The width can realistically be imagined to hold 5.56 x 45mm NATO ammo. The curve formation is derived from George B's AK-47 magazine, from whom I have permission to use. The actual curve matches that of the 5.56 x 45mm NATO magazine. As with all of my guns, the magazine is easily removable and is set deep into the magazine well, as close as it can get to the bolt.
3. Working bolt and carrier assembly
I love this part; the bolt is designed as closely as possible to the HK416's bolt. This also includes the same size spring, which happens to come from a 300-page spiral bound notebook. So the bolt can be pulled back and will shut when let go.
4. Chambered for the 5.56; you mean there's real ammunition in the dang thing?!
Yes, but this ammo was already fired, so there are no live rounds. However, I did replace the real slug with a dummy, LEGO pin slug. The bolt has two fingers that hold onto the 5.56 cartridge, which is fed into the chamber and locks into the barrel via the pin. Pull the bolt back and the ammo comes with it!
5. Changing barrels, from the 10.5" to the 14"
I spent two full nights figuring out how to make the floating barrel configuration, which allowed me to easily change barrels. However, I ran out of black, so the 14" barrel is mostly gray.
6. You mentioned a floating barrel?
The floating barrel was difficult to incorporate especially with the grip design covering the barrel. My first idea was to exclude having a barrel throughout the grip, but I soon realised that I needed a good barrel. As I said before, this took me two nights to figure out. I ended up combining two oppositely faced duplicate parts and snaped them together using 1x plates; it's quite complicated as you can imagine.

Pity about not firing, other than that this is one of the best Lego guns around, great job! I love the details like the rails on the handguard.
Had you thought of converting this into an M4 or M16? Since the bodies are virtually indentical, all it would need would be a different barrel, and handguard and maybe changes to the stock.
An M203 GL would be pretty cool to go with it as well.
thats like the coolest life size gun ive seen so far good job keep up the good work and ya sweet man make more maybe but if not o well its pretty sweet good job like i said its the sweetest life size gun ive ever seen so far
Wow, good to see more great stuff from you man. I see no major laws with your HK416, other than that the grip looks somewhat thin and small compared to the rest of your rifle. Otherwise, very nice. Are you going to put this on your Deviantart?
