5.56 ammo



Dating back to the 1950s, the 5.56x45mm NATO was designed as a response to evolving combat needs. Its lighter weight allowed soldiers to carry more ammunition into battle compared to larger calibers like the 7.62 NATO. Eventually adopted alongside the M16 rifle, the 5.56 NATO round proved itself in terms of effectiveness and adaptability. Its development, rooted in the .223 Remington, cemented its place as one of the most reliable calibers for combat and civilian use alike.

Whether you're looking for bulk 5.56 ammo for consistent range practice, specialized 5.56 NATO rounds for defense, or match grade 5.56 ammo for precision shooting, GRITR Sports has it.

Why Opt for the 556

Versatility: From training and target shooting to home defense, the 5.56 NATO round performs well in a wide range of scenarios. Its unique design ensures compatibility with most modern sporting rifles, especially the AR-15 platform. Just make sure you use proper rounds for your applications, usually, it’s 556 FMJ bullets or 556 ball ammo for range use and target practice or 556 hollow points for defense and hunting.

Types of 556 ammo: 556 bullets using FMJ design are either the M193 55-grain, known for speed and fragmentation, or the M855 green tip 62-grain bullets, known for greater penetration and “barrier-blind” performance. The M855 was designed to penetrate light barriers such as thin metals and cinder blocks but is less effective against body armor or for home defense due to over-penetration risks. It performs best with faster twist rates (1:7 or 1:8 barrels) for improved stabilization. If you're unsure which is right for you, start with lighter loads like 55 grain FMJ for general use. 

Performance: The 5.56 bullet is a high-speed projectile that achieves a flat trajectory, which makes it accurate at long ranges. Also, a combination of light weight and high velocity makes it prone to fragmentation, which results in significant tissue damage. For these reasons cartridge has become a favorite among civilian shooters for hunting small to medium-sized game (30-50kg) like coyotes or hogs, target shooting at distances up to 800 ft, and personal / home defense withhollow point ammunition that provides controlled impact, minimizing over-penetration.

Affordability and Accessibility: For shooters looking to buy in bulk, 5.56 bulk ammo options are widely available at competitive prices. A case of 556 ammo (typically 1000 rounds of 556) offers great value for high-volume shooters. With new options constantly on sale, finding cheap 5.56 ammo online has never been easier. For those prioritizing value, opt for 500 rounds of 556 or stock up with 20 rounds of 556 for casual range visits.

FAQs

What is 5.56 ammo used for?

Is there a difference between 5.56 NATO and .223 ammo?

Yes, 5.56 NATO operates at a higher pressure and has slightly different chamber dimensions than .223 Remington. While .223 can typically be fired from a 5.56 NATO chamber, using 5.56 in a .223 chamber can be unsafe due to pressure differences.

What does “green tip” 5.56 ammo mean?

Green tip 5.56 ammo, often labeled as M855, features a steel penetrator core for better penetration through barriers. It’s commonly used in tactical scenarios and is sometimes restricted at civilian ranges due to its enhanced penetration capabilities.

How is match grade 5.56 ammo different?

Match grade 5.56 ammo is designed for precision shooting. It uses high-quality components and tighter manufacturing tolerances, making it ideal for competitions or applications where accuracy is a priority.

Can you shoot 5.56 ammo in an AR-15?

What is the typical price of 5.56 ammo?

Prices vary between $0.35 to $1.00 per round, depending on the brand, quantity, and type (e.g., bulk ammo or specialty rounds like hollow point or green tip). Buying bulk packs, like 1,000 rounds, often reduces the per-round cost.
