These are the famous M855 green-tipped rounds known as Penetrator rounds. There’s a fair bit of misinformation out there about this ammunition, so here’s the scoop – or the true strength, as it were. The Penetrator is a mil-spec round categorized for use against personnel and light targets, but not vehicles. They have a lead alloy core that is made stronger because it’s topped by steel, hence the nickname. The ATF specifically exempts these rounds from the ban on AP, or armor-piercing, rounds because they simply are not capable of piercing armor. But they do have above-average penetration capabilities and are suitable for most rifles with a 1:7 twist, such as the M16A2, M4, and other 5.56 NATO-chambered weapons.

Since these are mil-spec rounds, they’re made by a military plant: Lake City Army Ammunition. The Lake City plant was originally founded by Remington in 1941 with the sole purpose of helping out the U.S. Army in World War II, and with the exception of a 5-year stretch after the war ended, they’ve been operating ever since. In 1985, the Olin Corporation took over the plant, which basically means Winchester was running it, and in 2001 the massive company ATK took over. As of 2007 their average annual production was 1.4 billion rounds, and they’re the largest producer of small arms ammunition for our U.S. Armed Forces. With those credentials, you can be confident of the quality and reliability of the 5.56 NATO you’re ordering, and it comes in a 1,000-round box.

These are 62 grain, which is the standard for M855 and medium-weight for the cartridge. They’re FMJ, so they’re great for training and plinking, just remember their extra penetration strength. Also remember that although a 5.56 NATO cartridge has nearly identical outer dimensions to a .223 Remington, they’re loaded to a higher internal pressure and cannot be fired from weapons not specifically rated for 5.56 NATO. These rounds have an outstanding muzzle velocity of 3,020 feet per second and make a serious impression with a muzzle energy of 1,256 foot-pounds. These are considered highly desirable rounds by a number of serious shooters, so get your order in for this 1,000-round case without delay.

(Although 5.56x45 NATO does fit in a .223 Remington chamber, the 5.56 is a military, high-pressure round and is not recommended for use in a .223 Remington chamber.)

Q: Is this armor piercing ammo?

Posted On: 3/28/13 By: Chris

A: While the tip of the bullet does contain steel in the core, this ammunition is not classified as AP (armor piercing). AP restrictions will not apply to these rounds. It should be noted that some indoor ranges may restrict this round due to the steel content. Even though these are not AP rounds, the steel will cause the bullet to penetrate metals that similar 5.56 rounds may not.
Q: What is the headstamp date on this ammo? It isnt visisible in the photo. Is it SS109 or XM855?

Posted On: 3/17/13 By: Howard

A: We have found that most of the brass markings from Lake City are 2011. The rounds have been manufactured within the last 18 months. The United States defines this round as the M855 while the NATO specifications reference this as the SS109 round. While some manufacturers will define one of these on their brass, Lake City usually includes the NATO symbol as well as "LC" and the year stamped.
Q: Is this steel core and whats the differnts from this and ur 500 fed green tip you sell it in 500 rounds but for a 1000 rounds of that its about 25 bucks cheaper than this and it looks like the same thing ?

Posted On: 9/17/11 By: david

A: This ammunition, manufactured at the Lake City facility, features a steel core bullet. Federal currently operates the Lake City facility under contract and both the 1,000 round count and the 500 round count are both manufactured at Lake City to the same specs. The only difference is the branding and packaging.
