Magpul MAG804-BLK Tactile Lock-Plate Type 2 Polymer, Black Finish, 1/8" Double Ridge for PMAG 10/20/30 AR/M4 GEN M3 & PMAG AR 300 B GEN M3 Floor Plates - 5 Pack

Keep your PMAG magazines locked and ready with the Magpul MAG804-BLK Tactile Lock-Plate Type 2. This five-pack of replacement floor plates works with PMAG 10/20/30 AR/M4 GEN M3 and PMAG AR 300 B GEN M3 magazines, giving you spare parts right when you need them. Whether you're rotating through mag sets at the range, building out a duty loadout, or just want backups on hand, having extra floor plates means you're never stuck with a broken or worn component.

The Type 2 design features a tactile lock mechanism and 1/8" double ridge that provides secure, repeatable engagement with your magazine body. The polymer construction with black finish matches your existing mag setup and resists wear from repeated field use and handling. Unlike cheap aftermarket plates that wear out or develop play, Magpul engineering keeps the fit tight and the function reliable over time.

These aren't just spares—they're insurance. A broken floor plate can compromise mag reliability or cause feeding issues downrange. Having a five-pack on hand means you can swap a damaged plate in seconds and get back in the fight. Keep a set in your range bag, truck, or spare mag case.

Frequently Asked Questions

Will these floor plates fit my PMAG magazines?

Yes—these Type 2 lock-plates are designed for PMAG 10/20/30 AR/M4 GEN M3 and PMAG AR 300 B GEN M3 magazines. If you're running a different generation or model, check the magazine body to confirm compatibility before ordering.

What's the difference between Type 2 and other floor plate designs?

The Type 2 design features Magpul's tactile lock mechanism and 1/8" double ridge, which provides positive engagement and a secure fit. This is the current standard for modern PMAG GEN M3 magazines.

Why buy a five-pack instead of single replacements?

A five-pack gives you spares at a better value. Whether a floor plate wears out, gets damaged, or you simply want backups across multiple magazines, having extras ensures you're never caught without a working plate when you need it most.
