Freedom Munitions 223 Remington SS109 Ammo - 62 Grain FMJ, 50 Rounds, New

Freedom Munitions 223 Remington SS109 ammunition was first used in the M16A2 rifle, replacing the earlier 55-grain M193 round with a heavier 62-grain projectile that offers better penetration against certain barriers. It is widely used in military-pattern rifles and remains a popular choice for training and range use due to its consistent accuracy and non‑expanding design.

This ammunition uses a non-expanding full metal jacket bullet with a steel penetrator and magnetic properties. The SS109 and similar M855-type projectiles offer greater barrier penetration than lighter rounds but behave differently on soft targets. The heavier 62-grain bullet typically remains intact after impact, transferring less energy than fragmenting designs.
