Winchester 5.56 NATO 62gr FMJ Green Tip M855 – 20 Rounds

Winchester M855 ammunition delivers the military-spec 5.56 NATO load built around a 62-grain full metal jacket bullet with steel penetrator core. The signature green tip identifies this as true M855 ball ammunition, designed for barrier penetration and improved performance through intermediate obstacles compared to standard M193 loads. This is a full-power NATO-spec load producing higher chamber pressures than .223 Remington — ideal for training, duty use, and applications where penetration matters.

Suitable for rifles chambered in 5.56 NATO or .223 Wylde. Do not fire in firearms marked .223 Remington only. Loaded in boxer-primed brass cases for reliable function in semi-automatic rifles and machine guns. Available in 20-round boxes and 1,000-round case quantities for range days or bulk storage.
