This bullet is engineered with a highly frangible, powdered-metal copper-tin core encased within a gilding metal jacket, offering unique durability and reliability. Unlike other frangible bullets without a protective jacket, MPG bullets stay intact through the demanding processes of handling, feeding and firing, especially in high-capacity magazines. This construction prevents the common issues of jammed actions and barrel obstructions, which are often encountered with traditional frangible rounds in modern AR-style rifles. Designed for dependable performance, MPG bullets provide smooth cycling and minimize maintenance concerns, making them a top choice for reliable functionality in high-performance firearms.
