There are a handful of sniper rifles in Call of Duty: Modern Warfare, but the M21 squeaks by most of the competition with its semi-automatic fire rate and 10-round clip. When you’re staring down the sights of an M21 and unleashing numerous shots, the recoil can get a bit hectic. But for those who can hold tight under pressure, the M21 presents massive killing power.
Unlike the more powerful sniper rifles (like the Barrett .50CAL), the M21 often takes two shots to bring down a target. Headshots are usually a one-hit kill, but you should get used to double-tapping when the enemy is in your sights. The M21 is also a decent sniper for intermediate players, as missing one shot won’t ruin your entire attack.
