Quick verdict
- The MTW Inferno Billet Gen3 feels premium straight out of the box, with an excellent magazine that feeds to the last BB.
- The battery is not included – it lives in the stock tube, and the cable and air line must be routed exactly right.
- My kit came without the black flash hider, so I fitted a short suppressor instead.
- I run it at 1.15 J with 0.30 g BBs; HPA consistency is noticeable from the first shots.
Watch the video
After hearing endless hype about the Wolverine MTW Inferno Billet Gen3 being the ultimate out-of-the-box HPA rifle, I finally got one. This is my first HPA replica – here is what’s in the box, how it goes together, and how it performed on the range and in a real game.
Unboxing: what’s in the box
It starts with a cool box. On top you’ll find a bag with a few gifts from MTW: some spare O-rings, a premium-feeling patch and a warranty card, plus an instruction booklet.
The magazine is a great one with a solid feel. It feeds to the last BB, and the rifle has an extra feature that recognises when the magazine is empty.
The lower receiver feels excellent, with a pretty tight selector switch. You’ll see a cable to connect the battery – the battery is not included, so budget for one (I use a 7.4 V 350 mAh Li-ion). The upper also feels great in the hand.
Assembly tips
- The battery cable and the battery itself are stored in the stock tube; position the cable exactly as shown in the video.
- The air line must also run on the correct side – get this right before closing the receiver.
- Insert the first pin – after that it becomes much easier. You might never need to remove this pin again.
- A metal plate presses the cable down so it doesn’t block the pin hole. Press firmly, check everything is in place and click in the second pin.
The line is now fed and waiting for the air tank (see the HPA setup guide).
One thing I didn’t like
The first thing I did was remove the flash hider. In most kits I’d seen online it was black, but mine wasn’t – a bit embarrassing for MTW to ship it without the black one. I replaced it with the short suppressor from my AEG.
Field test
I tested the rifle on the shooting range and in real gameplay. The final setup feels extremely good, with everything stable in place. I’m using 0.30 g BBs with the rifle set to 1.15 joules, and the consistency you get from HPA is noticeable straight away. Watch the video for the range groups and game footage.
Specs at a glance
| Model | Wolverine MTW Inferno Billet Gen3, 10" barrel |
|---|---|
| Power | HPA (high-pressure air) with Spartan electronics |
| Battery | Not included – fits in the stock tube |
| My setting | 1.15 J with 0.30 g BBs |
Verdict
- Pros: premium build and feel, excellent magazine, consistent shots, easy to tune with HPA, great support from Wolverine.
- Cons: premium price; no battery in the box; my kit shipped without the black flash hider; you need a full HPA system on top.
Is it the best out of the box? For me it lived up to the hype. Months later I had a feeding issue that MTW support solved quickly – I documented the fix in the MTW Gen3 disassembly guide.

Wolverine MTW Inferno Billet Gen3 (10")
My primary and my first HPA rifle. Tight, solid build straight out of the box – I run it at 1.15 J with 0.30 g BBs. Budget for a 7.4 V battery (it goes in the stock tube and is not included) and a shorter muzzle device.
Redline Mini SFR HPA Regulator
Takes the 800 psi coming off the tank down to the low working pressure the MTW engine needs, and lets me dial power up or down with a hex key. Compact enough to stay out of the way on the bottle.
