5.56×45 ammo like this by Prvi Partizan is a very popular choice among high-volume shooters and preppers alike. That’s because it offers superior Serbian-made quality for a comparably low price tag. But if all you need are a couple of boxes of this military-grade AR-15 ammo, the ammunition seeker team is just as happy to deliver!

“M193” just means that this is the most basic type of 5.56 ammo the U.S. Armed Forces would use during training and combat. Each cartridge sports a standard 55 grain full metal jacket projectile, with a nonmagnetic copper alloy jacket and lead core. This bullet ends in a tapered boat tail base, which helps it to retain more velocity and energy downrange. A boat tail also helps the bullet avoid getting blown off-course by annoying crosswinds.

The M193 projectile doesn’t expand in the traditional sense – although it does break apart into fragments if it hits soft tissue at a high enough velocity. Whether you set this ammo aside for an emergency or take it to the range as soon as you’re able, you’re bound to appreciate Prvi Partizan’s uniformly drawn, cut and tapered reloadable brass cases, as well as their sealed non-corrosive Boxer primers and low-residue propellant.
