Upgrade your Primaris Space Marines with jump packs, turret weapons, and Impulsor canopy kits with these conversion bits from TBD!
Welcome to the grimdark future where style and firepower go hand in hand! Whether you’re a newcomer just stepping into the 41st Millennium or a battle-hardened commander with more victories under your belt than an Ork has teeth, there’s always room for a bit more flair in your Space Marine army.
Tight Bore Designs has come through with some killer conversion kits that promise to take your minis from ‘standard issue’ to ‘Emperor’s finest.’ We’re talking about jump packs that would make even Sanguinius himself nod in approval, turret weapons that bring “overkill” to a whole new level, and a rear canopy that seals the deal on your Impulsor’s badassery.
Primaris Jump Pack Bits
Alternative Primaris Space Marine Jump Pack Conversion Bits: $17.99 (Discounts on bundles of 2 or more sets)
So, you’ve got your shiny new Primaris Marines, fresh from the battlefields of the 41st Millennium, and you’re thinking, “These guys are cool, but how do I make them epic?” Enter Tight Bore Designs with their alternative Primaris Space Marines Jump Packs conversion bits kit.
Let’s be real—every Space Marine is essentially a walking tank, but strapping a jump pack onto their backs? That’s like giving a battle-ready walking tank a jet engine. Here is how they actually look on an Assault Intercessor Space Marine (left) before hitting it with primer to bring out the details.
The jump packs are compatible with both Horus Heresy and Warhammer 40k models, making them perfect for those who want their Marines to stand out in both settings. Imagine your Blood Angels, the sons of Sanguinius, soaring through the skies, their jump packs roaring as they dive into battle with the fury of their Primarch himself.
These jump packs not only add flair but are an instant boost to the narrative you’re building on the tabletop. Whether you’re fielding the noble Ultramarines or the savage Space Wolves, these packs add a new level of badassery to your miniatures.
Printed to a high standard in high-quality resin, these bits are like the artisan bread of conversion kits—unpainted, unassembled, and ready for you to make your own. Your Space Marines deserve nothing less than perfection, and these jump packs deliver just that.
Tight Bore Designs Bits Are Perfect For Warhammer 40k
Gladiator Turret V2 Conversion Bits: (Varying Depending on Choices)
In 40k, subtlety is overrated. If your battle strategy leans more towards “more dakka,” then Tight Bore Designs has something right up your alley: the Turret V2 Conversion Bits. This kit is for the Space Marine player who understands that if one gun is good, two guns are better—and a turret full of guns? Well, that’s just common sense.
Imagine your Predator or Gladiator tank bristling with firepower. The Double Heavy Laser Cannon isn’t just for show; it’s the universe’s way of saying, “I see your armor, and I raise you a hole in the warp.”
Or perhaps the Double Heavy Assault Cannon is more your style, shredding xenos and heretics alike in a glorious hail of gunfire. Plasma cannons? Check. Bolters? Double check.
The best part? Each weapon set is designed with magnetization in mind. So, if you’re the kind of player who likes to switch things up between battles, you can easily swap out weapons to match the mission. Versatility meets devastation—a match made in the Emperor’s light.

El Camino Rear Canopy V1: $45.99
The Impulsor is a beast of a vehicle, but let’s be honest—it’s got a bit of a draft problem. That open-back design might look cool, but in the middle of a firefight, the last thing your Space Marines need is a breeze. That’s where the El Camino Rear Canopy V1 from Tight Bore Designs comes in, slamming the door on that little problem in style.
This kit isn’t just about function; it’s about flair. With multiple canopy tops to choose from, you can customize your Impulsor to fit the personality of your Chapter. Maybe you want a sleek, aerodynamic look for your Raven Guard or something a bit more rugged for your Iron Hands. Whatever your Chapter’s vibe, there’s a canopy top that fits like a power fist.
And for those who can’t commit? The kit’s got you covered with options for magnetization, so you can swap canopies faster than a Techmarine can recalibrate a servo-arm. This isn’t just a conversion kit; it’s a statement piece for your army.
The El Camino Rear Canopy V1 doesn’t just close off your Impulsor—it opens up a world of customization. Whether you’re driving into battle or just showing off your latest paint job, this kit makes sure your Impulsor is ready for anything the galaxy throws at it.
