The Ammo Inc 5.56 NATO 62gr FMJ (brand part no. 556062SS109-A20) loads a 62-grain SS109-pattern full metal jacket bullet, the heavier NATO-standard weight built for reliable feeding through AR-platform rifles at high volume. Ammo Inc positions this as a straightforward range and training round rather than a specialty match or hunting load. The 62-grain weight offers slightly improved downrange stability over the original 55-grain standard and pairs best with 1:7 or 1:8 twist barrels. Among rifle ammunition, it is a dependable choice for long range sessions.

Frequently Asked Questions

Is this safe to shoot in a .223 Remington rifle? This is a full-pressure 5.56x45mm NATO load. It is safe in rifles chambered in 5.56 NATO or .223 Wylde, but it is not recommended in rifles chambered specifically in .223 Remington, which are built for lower pressure.

Is 62-grain better than 55-grain for an AR-15? It offers slightly improved downrange stability and favors faster 1:7 or 1:8 twist barrels, but both weights function reliably in most standard AR-15 rifles.
