Availability: In Stock
Frontier Cartridge FR260 5.56x45mm NATO ammunition delivers military-grade reliability in a convenient 20-round box. Built with Hornady bullets, brass cases, and military-spec boxer primers, this 62-grain full metal jacket round is engineered for shooters who demand consistent performance across training, target work, and duty applications. Whether you're zeroing a rifle, running drills at the range, or stocking up for regular practice, FR260 ammunition offers the dependability you expect from serious centerfire rifle ammo.
The 5.56 NATO chamber is the standard across AR-15s, military rifles, and most modern sporting rifles, making this round universally compatible with the vast majority of centerfire rifle platforms. The 62-grain FMJ projectile is a proven performer—heavy enough to stabilize reliably in standard twist rates, light enough to deliver flat trajectories and manageable recoil, and constructed to penetrate and perform consistently through barriers and at distance.
Frontier Cartridge applies state-of-the-art loading techniques and rigorous quality control to every round, so you're not gambling with consistency. Each cartridge is loaded to exacting standards with military-grade propellant, ensuring velocity, chamber pressure, and ballistic performance stay true across the box and from box to box. That's the kind of uniformity that keeps your groups tight and your confidence high, whether you're breaking in a new rifle, training for competition, or simply putting rounds downrange.

Yes. Frontier Cartridge FR260 is loaded in 5.56x45mm NATO, the standard chamber for AR-15 rifles and most modern sporting rifles. It will feed, fire, and extract reliably in any rifle chambered for 5.56 NATO or .223 Remington (though always consult your rifle's manual for compatibility).
5.56 NATO and .223 Remington are similar but not identical. 5.56 NATO ammunition is generally safe to fire in .223 Remington rifles, but the reverse is not always true. Frontier Cartridge FR260 is specifically loaded to 5.56 NATO spec, so confirm your rifle's chamber before shooting.
Yes. The full metal jacket design and consistent construction make FR260 well-suited for range training, target work, and practice. The 62-grain weight provides a good balance of velocity and recoil for extended shooting sessions.
