Overview
Built for .224-caliber autoloaders, this 55-grain MPG bullet is intended for use in M4, HK416, and AR-15 type platforms, as well as other firearms with rifling twist rates of 1:9" or faster. Barnes’ Multi-Purpose Green design pairs a highly frangible powdered-metal copper-tin core with a gilding metal jacket, giving it a construction meant to stay intact through handling, feeding, and firing. That added protection is aimed at reducing the kinds of jams and plugged barrels that can occur with frangible ammunition. It is a practical option for shooters who want a bullet designed around reliable cycling in compatible firearms.

Considerations & Trade-offs
- Designed for M4, HK416, and AR-15 type autoloaders, so it is not a universal .224 option for every rifle platform.
- The stated twist-rate requirement is 1:9" or faster, which narrows compatibility with slower-twist barrels.
- As a highly frangible bullet, it is built around a specific use case rather than general-purpose bullet performance.
- Packaged as 100 bullets per box, so it is a component purchase rather than a complete loaded round.
