Battlefield Build Kits | Cannons, Catapults, Turrets, Racks & Bunkers

$4.99

Every battle needs more than an army.

The castle wall is quiet until the first stone lands. A field gun answers from the ridge. Beyond the smoke, a targeting light flickers across a turret pad. Every battlefield starts with the main build, but the small positions make it feel alive. Add the cannon guarding the gate, the rack inside the armory, the bunker holding the beach, or the weapon waiting at the edge of a distant world. Pick your piece. Build the next part of the fight.

Build the scene your way

Choose from 84 individual brick build kits spanning medieval sieges, wartime defenses, and futuristic bases. Each model is a small standalone build made to slot into a larger castle, battlefield, trench line, armory, or sci-fi outpost.

Testimonials

  • I was three figures short of finishing a diorama I'd been working on for months. Couldn't find the pieces anywhere reasonable. Brick Bros had exactly what I needed. fit perfectly, finished the scene the same week it arrived.

  • My son wanted a whole squad and the brand-name versions would've cost a fortune. These were a fraction of the price, snapped right onto his existing sets, and I didn't have to worry about the material. He hasn't put them down.
