M'tara-pattern focus rifle

The Type-52 Special Applications Rifle (or T52 SAR), more commonly known as the Focus Rifle is a Directed Energy Weapon used by the Covenant Empire in 2552.

Description
The Focus Rifle is a sniper-style weapon, that, despite its visual similarities to the Type-50 Sniper Rifle System, functions quite differently. It fires a continuous purple-tinted beam, similar in operation to a Sentinel Beam. The weapon is believed to be battery-powered, though the exact mechanism by which it functions is currently under investigation by the UNSC.

The laser will take approximately 1.5 seconds to kill a fully shielded Spartan, and is designed to emphasize more of a "tracking" skill set than other weapons because this weapon, being a sniper variant, does not feature any aim assist to compensate for its power. It is designed for ranged suppression rather than instant death, and is considered a power weapon. Its appearance and reticule is very similar to the Beam Rifle, with a 3.5-9.5x magnification scope.

Trivia

 * The beam-like nature of the weapon suggests that this weapon could have been reverse-engineered from a Sentinel Beam.
 * It is similar in name and firing style as the Scarab's Focus cannon, indicating that the cannon may be a larger-scale application of the weapon's technology.
