Here's another gun from me! The mechanism is very similar to Jack Streat's H&K 416, but I've completely redesigned the exterior. It features an extendable 6 position stock, removable 12 brick magazine, sling mounts (the front one can easily hold the weight of the gun, but the rear one unfortunately cannot), an opening dust cover, and line up sights (the rear sight can be switched to a smaller hole, just like the real thing). It measures 756mm in length, which is the exact length of the real weapon! You'll notice in one of the pictures that there is a broken technic half beam (and my entire collection of broken pieces ;) ). When I was trying to make a video of the mechanism in action, the hammer hit a beam in the gun (due to the absence of the right wall), and the half beam exploded. Anyways, I hope you like it!

First this gun is awesome! Second, If you still have this gun, can you post pictures with the barrel covers taken off so i can see how you attached them? Thanks, keep up the good work!

Im sorry to hear that, but good luck on your next build!

Quoting Bob Schwippert Mine are already loose but now I'm gonna try to use four, thanks for the tip! EDIT: I think it helped (its still not over, so I'm gonna try three rubber bands...) and somethimes the bricks with studs faced upwards in the mag don't shoot as far as the bricks with the studs faced downwards... don't think I'm giving up! (ps, this gun is in the assUAlt rifle folder, maybe you wanna say assAUlt?)
Sometimes the orientation of the brick does affect how it fires, and I'm not entirely sure how to fix it. But good luck, and thanks for correcting me!

Quoting Bob Schwippert I actually finished everything (only not the stock) but every time I shoot the weapon the top of the foregrip falls of and every eight shots the carry-handle too. maybe it's because my use of six rubber bands... did you had this kind of problems when building?
Yes I know what you mean. I ran into the same problem when designing it. The solution is to use different and/or fewer rubber bands. When the gun is not cocked, the rubber bands should be loose (not too loose, or they my get tangled up). And try using less rubber bands, try four. At one point, I actually only used one thick rubber band, and it gave quite a bit of power. Unfortunately it eventually snapped. I hope it works out for you!

Quoting Bob Schwippert Okay... Almost there! but where did you mounted the rubber bands? And you used a 5L axle for the press button, don't you think its better to use a 5.5L axle?
Look at this piece (http://www.brickset.com/parts/?part=4128557), the one closest to the front of the barrel. You'll notice there are three 4L technic axels through it to the other side of the barrel. The rubber bands mount on the top left axel (looking at the picture). And I used a 5L axel for the magazine release button so that when the button is pushed, the piece on the other side of the gun is flush (even) with the wall of the gun. With a 5.5L axel, the piece would come out further than the wall when pressed. (You can use either one, but I think the 5L is a little more realistic. Let me know if you have any troubles!

Quoting Bob Schwippert can you please make some more pictures of the front of the gun without the studded sides? or at least tell me how its made please. I'm trying to build this gun but I can't figure it out.
I've added a new picture to the page (third from the bottom). So basically, there are four panels that make up the handguard (each 6 studs wide). There are a few 6-stud-long technic axels crossed though the barrel assembly (they can be seen in the new picture). These bricks are attached to those axels (http://www.brickset.com/parts/?part=4233487), and the top and bottom panels are attached on those bricks. These bricks (http://brickset.com/parts/?part=4162443) are used to attach the two side panels. I really hope this helps, and I'm very sorry I don't have any better pictures.

I think I have a good picture of it on my computer, I'll see if I can find it today.

Quoting Bob Schwippert A little question, what does that part in front of the trigger and behind the magazine? (with that little yellow piece). Helping the hammer to stay in place? I also would love to see some sort of sniper from you!
Ah, that's just a little safety switch that can prevent the trigger from being pulled. A sniper? I'll probably build one sometime!

I love how powerful it is, and I would suggest you cover many of the technic holes with tiles. Small addition would make a huge difference.

It looks great on the outside , I might have to build jack streat's hk 416 after seeing this. Also speaking of broken parts one of the strongest parts I had break I a gun was a 3x5 L shaped lift arm in a folding crossbow pistol
