"Arrived in a decent time, the burst wizard 4 is awesome once I learned how to use it,love the multiple burst function.
by Luke P. on 02/01/2026
"The Burst Wizard 4 Mosfet works great as a fuse and a way to make your gun work Semi-Automatically even with your gun set to full-auto.

Semi-Auto in most AEGs is controlled by a cut off lever that will usually wear out/fail before rest of the gearbox and can be a pain to replace. Using the Burst wizard, you can set the burst to 1 BB and tune it so every trigger pull is a semi auto shot even though your gun is mechanically in full auto. It lets you bypass the cut off lever completely. Adds great longevity to the gearbox if you only use semi-auto. Also lets you convert a gun with only full auto into semi if needed.

The trigger feels much snappier and responsive when tuned in.

I'm unsure why this product page has no description but this product comes in a sealed plastic bag containing:
Burst Wizard 4 Mosfet
Signal Wire to wire the mosfet to the trigger contacts
4 heat shrink tubes to clean up electrical work
Tthe instruction sheet manual detailing all the different modes. There are 15 different modes, each with their own sub settings. Tons of tinkering you can do if you desire.

Took me about 20 minutes to setup and tune. Very satisfied with the experience. No other mosfet, that doesn't drop into your gearbox/trigger assembly, does what this one does. This is the perfect mosfet if you have a modified V2/V3 gearbox or don't want to hassle with a mosfet that drops into your gearbox.
