Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| Maruyama SCW-9 (native SCW-9 magazine well) | Direct Native Fit | Purpose-built for the Maruyama SCW-9 magazine well and feed geometry. Seat the adapter fully and confirm a positive seal against the loading nozzle for maximum gas efficiency and consistent feeding, without introducing drag on the reciprocating assembly. |
| Maruyama SPC-9 (straight-mag version) | Direct Native Fit (Shared SCW-9 Magazine Well) | The SPC-9 uses the same native SCW-9 magazine well and straight Maruyama magazine. Fit and tuning are identical — no additional adjustment required. |
| Maruyama SCW-9 / SPC-9 (GSeries / Glock-style magazine well) | NOT Compatible | The GSeries lower uses a Glock-pattern magazine well with different catch geometry. Use our Maruyama SCW-9 (GSeries) adapter for that configuration. |
| Maruyama MP9 (MP IX) | NOT Compatible | The Maruyama MP9 (MP IX) takes the same straight magazine, but its magazine well is different, so this adapter won't fit. Use our Maruyama MP9 (MP IX) adapter. |
| Maruyama SCW-9 (MP9-style magazine well) / KWA & KSC MP9 | NOT Compatible | The MP9-style SCW-9 lower uses a KWA MP9-pattern magazine well — a different magazine to the Maruyama MP9 above. Use our KWA MP9/VMP-1 adapter for that configuration. |
The SCW-9 is offered in three magazine-well configurations — native SCW-9, GSeries (Glock-style) and MP9-style (KWA MP9 pattern). This adapter fits the native SCW-9 well, as used by the SCW-9 and the straight-mag SPC-9. The Maruyama MP9 (MP IX) has its own adapter. Check which lower you have before ordering.
