Choosing among MOC parts & building pieces starts with a format decision: do you need a deep mixed supply, a vehicle-focused assortment, a themed scene to assemble, or a single character for display? The wrong choice can mean sorting loose parts when you wanted instructions-or buying a collectible when you needed construction pieces.
The split is clear: the two LEGO entries are bulk assortments, Modubrix is a new themed MOC build, and Bricks At War is a new custom minifigure. The listed prices span USD 20.00 to USD 142.00, a USD 122.00 spread, so the build format matters as much as the subject.
Quick take
- Open-ended MOC work: the LEGO random-parts bulk lot.
- Cars and trucks: the LEGO mixed-vehicle lot.
- A defined themed build: Modubrix Medieval Haunted Cemetery.
- A character-led display: Custom Alexander Hamilton Minifig.
The LEGO random-parts lot and mixed-vehicle lot favor sorting and parts selection; Modubrix and Bricks At War provide a more directed subject. That distinction is the fastest way to narrow the field.
Listed-price comparison
The listed prices run from USD 20.00 to USD 142.00, a USD 122.00 spread. The bars show relative price position across the four choices, not a product ranking.
| Product | Listed price | Price bar |
|---|---|---|
| LEGO 20 lbs Pounds Random Parts Pieces Building Plates Blocks Washed Bulk Lot | USD 142.00 | |
| LEGO Bulk Lot Mixed Vehicles Cars And Trucks Incomplete Sets Over 5 Pounds Parts | USD 79.99 | |
| Modubrix Mocs Brick Block Medieval Haunted Cemetery 2025 Parts Building Toys Set | USD 129.31 | |
| Custom Alexander Hamilton Minifig made using LEGO parts - Bricks At War | USD 20.00 |
Decision matrix
Use the build direction as the tie-breaker:
- Loose MOC experimentation: the LEGO random-parts bulk lot - mixed-color plates, blocks, and assorted pieces support sorting and invention; used condition is the trade-off.
- Vehicle scenes: the LEGO mixed vehicles cars-and-trucks lot - its subject and pictured assortment are specific; incomplete sets are the boundary.
- A themed assembly: Modubrix Medieval Haunted Cemetery - the MOC format and digital PDF instructions give the project a defined path; it is unassembled.
- Character display: Custom Alexander Hamilton Minifig - the named custom figure targets a single historical subject; it is altered and not a LEGO product.
Product notes
LEGO 20 lbs Pounds Random Parts Pieces Building Plates Blocks Washed Bulk Lot
If your project needs a broad supply rather than one subject, this LEGO bulk lot is built around a multi-color assortment sold by weight. The description includes plates, blocks, and assorted pieces across themes such as Star Wars, Marvel, Ninjago, City, Friends, and Jurassic Park, with MOC use called out. That breadth suits large-scale experimentation and sorting. The limitation is equally clear: the lot is used and random, so it is less targeted than a vehicle-focused lot or a themed build. Choose it when open-ended quantity matters more than a tightly defined scene.
LEGO Bulk Lot Mixed Vehicles Cars And Trucks Incomplete Sets Over 5 Pounds Parts
For builders who start with wheels, the LEGO Bulk Lot Mixed Vehicles Cars And Trucks Incomplete Sets Over 5 Pounds Parts keeps the subject centered on cars and trucks. It is described as genuine LEGO, and the lot contains everything pictured rather than a random selection. That focus can make it a practical starting point for a vehicle scene. The limitation is explicit: the sets are incomplete, the lot is sold as is, and the condition is used. This is therefore a parts-focused purchase rather than a complete-set route. Pick it when vehicle variety and the pictured assortment matter more than receiving a finished model.
Modubrix Mocs Brick Block Medieval Haunted Cemetery 2025 Parts Building Toys Set
Modubrix Mocs Brick Block Medieval Haunted Cemetery 2025 Parts Building Toys Set suits a defined scene rather than open-ended sorting. Its medieval haunted-cemetery theme and MOC designation give the project a clear direction, while the description says it is compatible with most major building block brands. The set is new, boxed, and has 2,025 pieces; instructions are supplied as a digital PDF rather than a printed manual by default. The limitation is the assembly commitment: it is not pre-assembled, and the listed age level is 14+. Select it for a themed display build with a defined subject; choose a bulk lot if loose mixed pieces are the priority.
Custom Alexander Hamilton Minifig made using LEGO parts - Bricks At War
For a character-led display, Custom Alexander Hamilton Minifig made using LEGO parts - Bricks At War delivers a very specific subject. It is custom-printed on authentic LEGO pieces and includes a custom-printed head, torso, and legs, plus a LEGO hat and other minifigure elements. The limitation matters for collectors: it is not a LEGO product, and the elements have been reused, repackaged, or altered. This is a single character collectible, not a source of loose construction parts. Choose it when Alexander Hamilton is the point of the purchase and a custom figure fits the build better than bulk bricks.
Final recommendation by use case
Choose the LEGO random-parts bulk lot for large, open-ended MOC projects; its assorted format is the clearest match for builders who want to sort and invent. For a vehicle-centered project, choose the LEGO mixed vehicles lot because cars and trucks are the organizing theme and the pictured assortment is defined. Modubrix Medieval Haunted Cemetery is the fit for an instruction-led scene build with a fixed subject. For a single character, choose Custom Alexander Hamilton Minifig made using LEGO parts - Bricks At War. Match the build format first, then use the USD 122.00 price spread to decide how much the project scope warrants.
