*The M99 shares its designation with the real-life Barrett Model 99 single shot sniper rifle, a derivative of the Barrett M107A1 anti-materiél rifle.

*Using the following formula: ''K = m(v*v)/2'', a round with 30.757MJ of muzzle energy and a muzzle velocity of 15km/s would have a mass of 271.78 grams or .6 lbs. This apparent discrepancy can be accounted for in one or both of the following ways:

**It can be assumed that the weapon is not normally fired at its highest-rated output, as repeated firings could lead to barrel deformation due to both the electromagnetic repulsion and friction-induced heat of the projectile traveling the length of the barrel. Even if fired at 75% of full output, a round will still overpenetrate obstacles and inflict catastrophic damage to soft targets.

**The 5.4mm designation refers to the ''diameter'' of the round, not its length. With this in mind, it is likely that the round is significantly longer than it is wide & is composed of a super-heavy alloy such as depleted uranium, in order to further enhance its destructive potential by concentrating more mass in a smaller area, which would allow more kinetic energy to be delivered to the target.
