CMMG PS90 Magazine Adapter — The Simplest PS90 30 to 50 Round Conversion on the Market
If you run an FN PS90 and want more capacity without the cost and hassle of buying new magazines, the CMMG adapter plate PS90 magazine conversion is exactly what you need. At just $14.95, this is one of the most cost-effective upgrades available for the platform — and the installation takes less time than loading a magazine.
What the CMMG Thread Adapter PS90 Actually Does
The cmmg ps90 thread adapter is a replacement spacer that fits inside your existing 30-round FN PS90 magazine. When installed, it converts the magazine to hold 50 rounds while retaining the factory follower and spring. No new magazines required. No gunsmithing. No complicated tools.
The installation process:
- Remove the magazine floorplate
- Replace the factory spacer with the CMMG magazine adapter
- Reinstall the floorplate
- Load and go
That is the complete process for a ps90 30 to 50 round conversion with this adapter.
Why This Adapter Stands Out
The cmmg adapter plate ps90 magazin is designed to work with the factory internals — no modifications to the feed lips, follower, or spring are required. This keeps reliability consistent with the stock configuration. You are not reinventing the magazine; you are simply extending what it was already doing.
At $14.95 per adapter, the math is simple: convert what you have rather than buying new 50-round magazines at a significantly higher per-unit cost. The money saved goes straight back into ammunition.
