Does a 1,698-piece brick gun actually earn its shelf space? In the case of the MP5 Building Block Gun, yes — if you want a long, rewarding build and a display-grade replica. It does not fire (that is the Uzi’s job), but its adjustable scope, detachable magazine, and pullable bolt make it the most mechanically detailed building block gun at POPLAYO.
This review looks at the MP5 toy gun the way a builder would: piece count, size, working details, build experience, and how it compares with the rest of the POPLAYO brick gun lineup. All specs come from the product page — no guesswork.

| Type | Static display model |

What You Are Actually Building
Three working details separate the MP5 from a plain brick gun replica:
- Adjustable scope — the optic repositions like the real thing.
- Detachable magazine — slides out for extra realism.
- Pullable bolt — the charging handle moves, so the finished model feels mechanical.
At roughly 48cm, the finished MP5 is substantial. It is the heaviest project in POPLAYO’s building block toy gun range: the G17 is a quick first build, the Uzi adds 359 pieces with a firing mechanism, and the KSV matches the MP5’s scale at 1,502 pieces with swappable barrels and a folding stock.
Build Experience: What 1,698 Pieces Feels Like
- Organize first. Sort pieces by color and size — it saves hours of hunting.
- Follow the manual in order. Build the frame, then the working details like the bolt and magazine.
- Test as you go. Check the magazine detaches and the bolt pulls before locking everything in place.
- Display, don’t drop. The model is sturdy but designed for display, not rough play.
Most builders spread this across several sessions. That is the point — it is a project, not a ten-minute toy.
MP5 vs the Rest of the Brick Gun Lineup
| Model | Pieces | Fires? | Standout Feature |
|---|---|---|---|
| G17 Building Block Pistol | Handgun build | No | Quick first build, movable slide |
| Uzi Building Block Gun | 359 | Yes | Only firing brick gun |
| MP5 Building Block Gun | 1,698 | No | Biggest build, adjustable scope |
| KSV Building Block Gun | 1,502 | No | Swappable barrels, folding stock |
Choose the MP5 for the single biggest, most detailed build. Choose the KSV for comparable scale with more reconfiguration. Choose the Uzi for a working blaster, and the G17 for a quick, affordable project.
Who Should (and Shouldn’t) Buy It
Buy it if:
- You enjoy long construction projects and want a museum-quality result.
- You collect realistic toy gun replicas for display rather than play.
- You are buying a memorable, hands-on gift for a hobbyist.
Skip it if:
- You want a toy that fires out of the box — pick the Uzi or a foam dart blaster instead.
- You only have one free evening — this build takes multiple sessions.
