The verdict

This is the second UCS AT-ST ever, and it fixes the wobbly legs that plagued the old 2006 version, so it actually stands there like it means business.

What it can't fix is that the chicken walker is basically a gray box on gray legs, and that's the whole personality. If you grew up loving the Endor scout walker, you'll be grinning. If you want color and clever surprises, this one asks you to find joy in shades of light and dark bluish gray.

Best for: Endor-loving Star Wars collectors who want a rock-solid UCS display piece

The full review

What it is

Some LEGO® sets win you over with a rainbow of new parts, and this one does the exact opposite. Empty the bags of the AT-ST Walker and you're staring at a sea of gray, light bluish gray, dark bluish gray, and just enough black to keep things interesting. That sounds like a knock, but it's actually the point. The Imperial scout walker from Return of the Jedi was a drab military machine, and set 75417 commits to that look with total conviction. This is the second Ultimate Collector Series AT-ST ever made, following the beloved 10174 from all the way back in 2006, and the nearly two decades of progress really shows. At 1,513 pieces and 37cm tall, it's the biggest and best brick version of this walker you can build.

The catch

Now for the honest bits, because there are a few. The price is the first hurdle. Two hundred dollars is a lot for a model built almost entirely from plain gray bricks, and several reviewers gently suggested waiting for a discount before you commit. The proportions are the second sticking point. Look closely and the head sits a touch too big, the feet are chunkier than they should be, and the legs read a little thick, so purists who know every frame of Endor will spot it. And then there's the articulation, or rather the lack of it. This walker is built to stand stable and proud, which is lovely for display, but it doesn't pose or stride the way the real chicken walker skittered across the forest moon. You set it down, and there it stays.

Who it's for

So who's going to be happy here? If the AT-ST is one of your favorite Star Wars machines, and you want a sturdy, screen-accurate centerpiece that won't topple the moment someone walks past the shelf, this is an easy yes. It's a calm, meditative build with a satisfying payoff, and the stability alone makes it a better display piece than the old version. If you're hunting for exciting new molds, bright colors, or a walker you can pose in a dozen action stances, you'll probably feel the gray creeping in. My honest take is that this is a very good set with real caveats, one that rewards Star Wars love more than it rewards pure building thrills. Grab it on sale and you'll feel great about it.

The parts story

What the build is actually like, and the pieces worth knowing about.

The build runs a comfortable seven to eight hours if you spread it across a couple of evenings, and it moves through the walker in logical sections. You start low with the feet and the sturdy leg assemblies, which is where a lot of the engineering hides, because keeping a top-heavy body upright is the whole challenge with a chicken walker. From there you work up into the boxy main body and finally the iconic head, and there are a couple of genuinely clever angle techniques tucked in to shape those slanted panels. It's not a puzzle box of a build, and some sections are straightforward repetition, but it stays engrossing in that classic UCS way where the model grows into something imposing on your table.

Piece-wise this is a study in gray, and that's exactly what makes it authentic. You're working with big quantities of light bluish gray and dark bluish gray in slopes, plates, and panels, with black used sparingly for depth. The standout feature isn't a single rare mold, it's the payoff of that restraint: empty the bags and it's almost entirely gray, which keeps the Star Wars immersion completely intact with no stray bright parts breaking the illusion. The head lifts off to show a properly detailed cockpit with seating and controls, and a hatch opens on top for Wookiee or driver access. Value-wise, 1,513 pieces for $199.99 lands around thirteen cents per part, which is on the pricey side for such ordinary bricks, so the worth here is in the finished silhouette rather than the parts bin.

Fun facts

01This is only the second Ultimate Collector Series AT-ST ever made, arriving nearly twenty years after the original 10174 from 2006.
02It was designed by Niels Bundesen and stands about 37cm (14.5in) tall, making it the largest LEGO AT-ST to date.
03The single included minifigure, the AT-ST Driver, gets a dedicated little display stand beside the plaque because the walker itself is far too big to seat him inside for viewing.
04The model is built almost entirely in shades of gray on purpose, staying faithful to the drab Imperial scout walker seen stomping through the forest moon of Endor in Return of the Jedi.
