20 Rounds of 55gr Frangible ZGQ3302 5.56x45 Ammo by Winchester

The M16 was designed in 1962 and immediately began to see use in 1963 by soldiers during the Vietnam War. The M16 is fairly lightweight considering its size and is an air-cooled, gas-operated, magazine-fed rifle that has a rotating bolt and is chambered in 5.56x45mm NATO. It’s a selective-fire rifle that has gone through a number of incarnations, being made for single-fire, three-burst, and full-auto modes, and in 2010 the U.S. Army went a step beyond the popular military rifle with the creation of the M4, which is simply a smaller version of the M16. The 5.56 NATO round the rifle is chambered in is by far superior to the 7.62x51mm round of the old M14 in part because it’s capable of performing at a wider range of temperatures but also because it creates a more devastating wound track. If you have a civilian rifle chambered in 5.56 NATO, you have the M16 to thank for its initial creation.

55 grain makes these lightweight rounds, but they are the weight originally made for the cartridge. These aren’t just any rounds, though, they’re frangible, meaning they’re designed to shatter entirely on impact. Unlike most bullets, which are typically made of lead and retain their mass on impact, a frangible round is usually made of pressed copper and fragments entirely on impact. Frangible rounds are excellent for close-quarters training and steel targets because they drastically reduce the risk of ricochet. In addition to their deterring ricochets they also solve the problem of over-penetration. This ammunition moves with fantastic speed with a muzzle velocity of 3000 feet per second and hits with impressive force with a muzzle energy of 899 foot-pounds.

There are 20 frangible rounds in this box of ammunition. These are Winchester’s ZGQ3302 rounds which are made to NATO specs and are not suitable for rifles chambered in .223 Remington. All of Winchester’s ammunition is made in America and manufactured according to strict specifications. Since their founding in 1866 they’ve built a stellar reputation for themselves, manufacturing both firearms and ammunition to a high standard. Winchester is truly a legend in the gun world, and if you want to keep your 5.56 NATO-chambered rifle loaded with frangible rounds from a legend, get your order in for these Winchester rounds 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.)
