There's actually no such weapon as the M21 EBR in real life - the weapon featured in game is more usually known as the Mark 14 Model Zero Enhanced Battle Rifle, or the M14 EBR. M21 refers to another sniper weapon system based upon the M14 rifle - and was in fact featured in COD 4. Presumably Infinity Ward used the M21 designation to emphasise this weapon's place in the sniper rifle category. In any case, the EBR is an improved variant of the venerable US-designed M14 battle rifle, originally designed in 1957. The EBR variant was first seen in 2001. Like most western battle rifles (such as the G3 and FAL) it fires the NATO standard 7.62 by 51 millimetre rifle cartridge. In real life the M14 EBR is more of a designated marksman's rifle than a sniper weapon, normally used as part of a squad to provide accurate fire beyond the typical assault rifle's capable range. This is reflected somewhat in-game, as the M21 EBR deals the lowest effective damage of all of the sniper rifles; Although the base damage is the same, the multipliers mean that this weapon has the smallest one-hit-kill profile. Unsilenced, with stopping power, a hit to the head, neck or upper chest will kill. Otherwise, the one hit kill zone is reduced - or when silenced without stopping power, eliminated entirely. However, the EBR also has the lowest recoil, meaning that you can more easily follow up with additional shots if required. This, coupled with the lower damage, means that most people familiar with the M21 EBR will instinctively fire two shots quickly - if both connect you'll be guaranteed a kill, otherwise depending on your loadout you might get lucky and kill with just one shot. Magazine capacity is generous for a sniper rifle - it's tied with the Barrett in this regard. The 10 round capacity is more useful with the EBR though,
