Winchester 5.56mm 62 gr M855 Penetrator FMJ 20/Box

This M855 5.56 Penetrator ammo from Winchester comes in a box of 20 rounds. The green-tip M855 round is currently in use by the U.S. Military, and has much-improved penetration characteristics over the old M193 5.56 55-grain projectile at all ranges, resulting in higher retained velocity and greater accuracy at long range.
