Everything you need to know about how to make, build, and buy alternative LEGO Warhammer 40k kits, from fan creations to custom sets and collaboration guides!
No official LEGO Warhammer 40k sets exist right now. And who knows if we’ll ever get an official collab? For now, you’ve got three ways to get your Warhammer 40k LEGO fix: fan-made MOCs with downloadable instructions and parts lists, third-party armor bits and custom minifigs, or creator galleries if you’re still figuring out what you like. Just pick how much you want to build, and the links below should get you going.

What “LEGO Warhammer 40k” Actually Means (3 Ways to Get Into It)
When people talk about LEGO Warhammer 40k, they usually mean three different things. And depending on what you’re looking for, knowing the difference can save you some time and hobby money.
- Build Your Own: MOCs, instructions, and parts lists. Want to build your own 40k models out of LEGO? This is where you start. Creators share their designs, downloadable instructions, parts lists, and sometimes premium files you have to pay for. If you like building stuff yourself, this is probably your thing.
- Ready-Made: Third-party minifig armor and bits. Not looking to build everything from scratch? You can find custom helmets, pauldrons, weapons, full armor sets, and other accessories that make regular LEGO minifigs look a whole lot more like 40k characters. If you’d rather pick up some ready-made figures or bits, start here.
- Get Inspired: Inspiration and editorial showcases. Maybe you just want to see what other hobbyists have come up with first. These galleries, features, and creator pages are great for checking out different designs and figuring out what you like. It’s worth having a look before you start throwing hobby money at parts.

Where to Get Your LEGO Warhammer 40k Kits & Ideas
- Rebrickable (Instructions + parts lists): Of all the sites, Rebrickable might have the most ready-to-go LEGO-style kits. It is one of the best places to find MOCs with downloadable instructions, parts counts, and both free and paid instruction options, depending on the creator.
- Etsy (Armor/bits + some digital instructions): Like Rebrickable, Etsy has pre-made sets, cool mini-figures, bits, armor parts, and sometimes digital MOC instructions. Just verify exactly what is included and how the seller phrases compatibility.
- 01BigBricks (Ready-made minifigs): This is more buy-than-build, with ready-made Warhammer 40k-style minifigs and accessories. Good if you want something fast for display, not so much if you want the full build workflow.
- eBay / Amazon (Mixed): Sometimes you can find great stuff, other times not so much. Quality varies a lot, so check reviews, seller history, listing details, and product photos before buying.
- Communities: Websites like BitzStore and the 40k LEGO modder community are better treated as idea hubs, troubleshooting stops, and inspiration sources. More on those in the Online Communities section below.

Pick Your Scale (Minifig vs Micro vs Display)
- Minifig scale: Best for squads, characters, armor bits, and custom troops.
- Micro scale: Better for tanks, Titans, and battlefield scenes without needing a mountain of parts.
- Display scale: Best for centerpiece builds like a Land Raider, Dreadnought, or faction showcase piece.
The Rebrickable Workflow (6 Steps)
Take LEGO’s My Own Creation (MOC) system, for example. It’s basically a playground for fans to build whatever their heart desires, like a Space Marine squad or a Chaos Dreadnought.
- Pick your build. Search Rebrickable for the faction, unit, or vehicle you actually want to make.
- Check the listing. Look for part counts, finished photos, and whether the instructions are free or paid.
- Download the instructions. Make sure you are getting a real build file and not just a cool render.
- Review the parts list. This tells you what you already own and what you still need to source. Check what you’ve already got before buying anything else.
- Source the missing pieces. Use the parts list as your shopping map instead of guessing. Sort out the standard bricks from the custom armor bits, then just order what you’re missing using the options above.
- Build and tweak. Once it is on the table, adjust details, swap bits, and make it look more 40k.
Build Tips That Make It Read “40k”
- Go big on silhouettes: chunky shoulders, oversized weapons, and broad vehicle profiles do a lot of the work.
- Keep the faction cues obvious: a Blood Angel should not read like a random sci-fi soldier, and Orks should look loud and brutal even in brick form.
- Do not overcomplicate the first build: clean shapes usually beat fragile detail spam.
- Use reference images: compare the build to actual 40k art or minis so it still feels like it belongs in the setting.

Inspiration Galleries (What “Great” Looks Like)
Warzone Studios makes some big Warhammer 40k LEGO Space Marine MOCs and display pieces, and there’s plenty to borrow from their designs. One thing you’ll notice with builds like these? The more straight lines you use, the easier it usually is to get everything looking clean.
Then you’ve got Jerac, who’s been making LEGO Warhammer 40k models for over a decade now. His gallery has everything from Blood Angels to Ork hordes, plus battlefields that look like they’ve survived a whole campaign. Want to see what other builders are doing? Brothers Brick has features and builds from all sorts of creators.
Builders & Tutorials (Step-by-Step Creators)
If you need some more inspiration on how creators actually make these massive sets, YouTube’s a good place to start. Creators like Kos Brick show off their builds and walk you through making your own, whether it’s a LEGO Land Raider or a Warboss’s trukk.
Community Help (Reddit)
If you’re stuck on a build the 40k LEGO modder community on Reddit is a good place to ask. Just tell people what you’re building and what’s giving you trouble. Whether it’s finding parts, getting things to fit, or figuring out if the design will even work, they can be pretty helpful. Just keep in mind, the more specific you are, the better the answers you’ll get.
Beware of the Knockoffs?

Now, if you’re not up for building your own, you might be tempted by the world of knockoffs. But tread carefully; there’s a reason these unofficial sets are so cheap.
We actually tried the sets pictured here in our Alternative 40k Space Marine LEGO Review, so give that a look before buying anything similar.
Before You Buy: 7-Point Checklist
- Real photos vs renders: Make sure you are seeing an actual product and not just polished mockups.
- What’s included: Check whether the listing is for a physical set, instructions only, or just armor bits.
- Reviews and returns: Look at what buyers actually said and whether you have any recourse if the quality is rough.
- Compatibility wording: Read how the seller describes the fit with standard bricks and minifigs.
- Shipping origin and time: Some listings look cheap until you notice the delivery window from the far side of the galaxy.
- Too-good-to-be-true pricing: If the price looks absurdly low, there is usually a reason.
- Seller reputation: A sketchy seller with vague photos and no history should not get your hobby money.

Sites like AliExpress are full of Warhammer 40k LEGO figures and vehicle kits that look the part, but the quality can be… let’s say, variable.

Sometimes, you get something that’s passable, and other times, it’s more cursed than a Chaos-tainted servitor. And here’s the kicker: neither LEGO nor Games Workshop licensed these knockoffs.

How to Spot AI “Box Art” Fast
- Impossible brick geometry: pieces look cool until you realize they do not actually connect in the real world.
- No seams or studs where expected: real LEGO builds usually show their structure somewhere.
- Uncanny repeating textures: AI loves cloning detail in ways that look slick at first and wrong on a second pass.
What to Do Next (Turn AI Into a Buildable Plan)
Use AI as concept art, then go find a real MOC with a parts list and instructions. That is the difference between “cool image on the internet” and something you can actually get onto your hobby desk.

In the Meantime: Best Path to Build or Buy Now
Want some LEGO Warhammer 40k on your shelf right now? You’ve basically got two options. Grab some Rebrickable instructions and a parts list if you want to build the whole thing yourself, or pick up armor bits and minifig accessories if you just want something cool to display without all the building.
