#EnhancedPerformance

IMI Systems has published a news release telling about their new enhanced performance 5.56x45mm ammunition called 5.56APM (Armor Piercing Match). The round is completely developed and they are already manufacturing it. It is supplied to IDF (Israeli Defense Forces) for testing and evaluation.

While soldiers are typically lauding the M855A1 Enhanced Performance Round, it has come at a cost of long-term durability and reliability of the M4A1. The M855A1 exposed steep tip loading is substantially different from its predecessor, the venerable M855 steel-core, which had been in-service for decades prior to the change-over. The high-pressure load to eek out velocity has been burning through barrels quickly and another issue reared its head from the steel tips gouging the upper receiver’s extended aluminum feed ramps over time.
