M855 is often referred to as green tip ammo for its special color coding (the projectile itself is painted green at the tip). These 5.56 cartridges push a 62-grain bullet designed with a boat tail, lead

core, and a special steel “penetrator” tip. The specified muzzle velocity of M855 ammo is roughly 3,020 feet per second depending on the manufacturer. The primer and case mouth are

chemically sealed, just like M193 ammunition.

The AR-15 is America’s most popular rifle, and for good reason. It’s lightweight, accurate, easy to shoot, and you can run it as a rifle, carbine, or pistol, thanks to its modular design.

An AR-15 can also shoot a wide variety of 5.56mm ammunition. Some variants are set up to run 40-grain small game loads. Other mil-spec rifles prefer heavier 77-grain freedom pills that work

well with suppressors.

Today, we’ll be taking a look at two of the more popular types of 5.56mm ammunition for the AR-15. 62 grain M855 vs M193 running at 55 grains.

The , a 5.56 mm Ball ammunition, is an enhanced performance round for today’s combat and training environments. It works with the M4 Carbine, the M249 machine gun, and the H&K

and M16A2 rifles. It is suitable for use in most weapons with a 1-in-7 barrel twist, , Buy M855 .

The has a copper-jacketed steel core, differing from the previousround which has a lead core. The so-called “green ammo” not only has increased penetration of armor and hard

targets, but allows the Army to be more environmentally friendly on its ranges and training environments.

The is optimized for the shorter-barrel M4 where the standard  was optimized for the M16. The powder burns faster

and creates more pressure, and has the effect of reducing flash.

The round yaws like the , but its yaw is more consistent and predictable, meaning its terminal effects are not yaw dependant.

The Army plans to replace its entire inventory of rounds with the  round.
