Simple to Build Lego Guns

Updated on September 14, 2014

How to build a simple Lego gun?

There are a LOT of awesome working Lego gun builds out there - but most of them are far too complicated to build (using bricks I just don't have laying around the house).

This page focuses on instructions for simple Lego guns that you can actually build with bricks you probably have laying around the house - and if you don't, I'll tell you where to buy Lego gun sets to make working Lego guns (because Lego doesn't sell them).

In my family we've built several Lego guns that have a similar problem (breaking apart on impact). But we've lessened the problem by softening the impact with a rubber Lego technic wheel.

As a family-friendly company, Lego's policy is to not make 20th century weapons (guns included).

Obviously there is a market for working Lego gun kits and realistic Lego mini-figure guns. Most boys go through a phase where they are very into war and war games.

BrickArms was created when the owner's son wanted to replicate a World War II battle in Lego and was disappointed that he couldn't do it with the Lego figures he already had. BrickArms now produces Lego-compatible weapons.

BrickGun sells realistic looking Lego gun kits (so that you can build them yourself. The guns do not shoot bricks. However, BrickGun's MAC 11 Rubber-band kit does shoot rubber bands.

      I used to my guns with lego when I was kid. But not as real looking as these. Great lens, makes me wish I was 8 years old again.

      I need instructions on how to build a lego gun that shoots anything by using just some of these pieces: some 2 by 2s, some 4 by 4s, some 1 by 2s, or some 1 by 4s, and a couple of rubber bands. (NO TECHNIC PIECES)

      @anonymous: Sorry about that. It looks like the website owner took down the instructions for that build :( I'll see if I can replace it.

      For the 'Simple Lego Rubber band Gun' I click the 'Click here for the instructions' then it goes to another website then it doesn't come with instructions! WHY??

      I made one using a technic motor (9v square style - 2000 style), that spat out toothed racks from a hopper above. It jammed about 1 in 5 times, but just about worked. I only had about 10 or so, so it quickly expended the ammo - and had a range of centimeters. I now have a bag of the lego basketball/footballs - not tried making a way to fire them though...
