Overview
The Bushmaster Carbon 15 is an Assault Rifle added in the 2/17/12 patch as a preview sale. Its design is heavily based off the older, more widely-known AR15 platform, but is much lighter and more versatile. In game the recoil is not really 69 its actually 65 or less. The recoil is highly controllable, unlike what the stats show. This gun has the current top rate of fire for an AR at 78. The Carbon 15 has a huge damage drop off after 50 meters. This is due to it's SMG/Assault hybrid qualities.
