Crown / Samducksa CWL-303MJ-DX — Clear White
The 303 is one of the foundation levers of Samducksa’s Crown 300 series, the Korean levers that grew up in South Korea’s Tekken arcades. It is also the base that famous Korean Tekken player Crazy Dongpal used for his own signature lever. Samducksa says precision-made parts raise its input reliability, and that it is optimised for Tekken while still tuned to suit other fighting games.
The MJ build pairs a short low-profile collar with a Japanese-style mounting plate, so you get the accuracy of a collar while still fitting most fightsticks built around Sanwa JLF mounting.
What the model code means
- M: short, low-profile collar. You keep the accuracy of a collar while still fitting cases built for Japanese levers.
- J: Japanese-style mounting plate with holes that line up with most Sanwa JLF mounts.
- DX: “deluxe” build, with Samducksa’s DX bobbin inside the tension grommet and a DX shaft with a removable clear bat top.
How it feels
Instead of a spring, the shaft sits in a silicone tension grommet. It feels elastic and springy with a fast snap back to neutral, which suits Tekken movement and backdashing, while still handling quarter-circles and half-circles smoothly in 2D games. The lever comes with one grommet fitted. Samducksa also makes 25, 35 and 45 tension grommets, sold separately, if you want to change the weight later.
