Let’s dive into everything you need to know about the CMMG adapter plate PS90 magazine what it is, how it works, how to install it, and where to get the genuine ones.
What Is the CMMG Adapter Plate for PS90 Magazines?
The CMMG adapter plate is a specialized component that modifies your rifle’s magazine well so it can accept PS90 magazines. PS90 magazines have a very unique shape and feed system that doesn’t work with standard magazine wells on most rifles, including many CMMG models.
Without the adapter, you simply can’t fit these magazines into your gun, or if you do, they won’t lock properly or feed rounds reliably.
How It Works
- The adapter plate physically changes the size and shape of the magazine well.
- It makes the magazine lock into place firmly.
- It ensures the cartridges feed smoothly without jams.
Understanding the PS90 Magazine
The PS90 magazine is distinctive and popular for several reasons:
- High capacity: It holds 50 rounds of 5.7x28mm ammo, much more than a typical rifle magazine.
- Horizontal feed design: Instead of feeding bullets from directly below, the magazine feeds from the side, which is quite unique.
- Durability: Made from tough polymer, they’re lightweight yet rugged.
This design is why PS90 magazines are loved in tactical and competition shooting circles. But their shape means you need an adapter plate to use them in many rifles.
